I started taking Alli and within the first couple of weeks I started to experience dizziness. I stopped taking it and it went away.

I started taking it again, and the same thing happened, I was under the impression that the drug does not enter the bloodstream, so why was it making me so lightheaded? I haven't tried it again, as this was one side effect I was not expecting.

I was on Alli for about 2 months. The first month I was on Alli, I lost about 10 lbs. Since I reached my desired weight I stopped using it and ate healthy.

I wasnt eating 15g or less of fat after the Alli, but I wasn't overeating. I gained all the weight I had lost.

Alli is great if you need something in the back of your head telling you "DONT EAT THAT, YOU'LL REGRET IT LATER" Other than that, I think that the troubles of frequent trips to the bathroom and tummy pains isn't necassary.

If you're an active person who is always outside or running around, I dont think Alli is for you. After a meal, just make sure you have a bathroom near because the side effects are not pleasant.

When I DID lose the weight I was working and going to school and the only food around was Subway. I stuck to eating the FreshFit Subs which are usually 6g of fat and are filling..I suggest that's the best way to go.

Good luck!

I have been on Alli fo about a week, and have not experienced any side effects. I eat a healty diet, so that could be why. I need to lose about 20 lbs., and had hit a plateau with "eating healthy & exercise". I haven't been on a scale since I started, so will check this weekend to see if I have any weight loss. You do have to watch what you eat; in fact, it's not a diet, but a lifestyle change. If you lose weight on a "diet", then go back to bad eating habits, you will always gain the weight back!

I tried Alli pills because there was so much hype about it and actually in the end it worked. I don't know how much weight I lost but I lost enough to notice.

However, the side effects are not so great. I got, oily spotting, and bowel problems and, yeah it was pretty scary but it does what it says.

It doesn't allow you to absorb all the fat you consume, but that's because you'll be leaking in a bit. So I guess I lost weight because of my fear of eating fatty foods.

I've tried other diet pills, but so far this is the one I'm sticking to to lose weight. Hope this helps.

I was not expecting a "miracle drug" and I don't believe that Alli is. Personally, it gave me a boost in starting to improve my dietary habits.

Frankly, I heard about the possible side-effects and determined that, for me, the trade-off wouldn't be so bad. I've been miserable being fat. People who have gastric surgeries to lose weight go through a terrible ordeal. I expected some "cost" to working toward being healthy again.

During those first few days on Alli I did have some of the symptoms. It was manageable. Only one "mess," and I learned quickly not to trust the urge to pass gas during times of cramping and "churning."

After several days those symptoms went away and I rarely have anything like it now.

What I learned during those uncomfortable bouts was that I just can't eat huge amounts of fat. But I can eat enough to have some fun if I am taking the Alli. I can diet and exercise without being too rigid or hard on myself.

I have lost about 30 pounds in three months. Some days I take the maximum dosage. Other days I don't need to take any because I don't have the urge to eat much fat.

The "miracle" aspect of this medication has been that it has assisted me in changing my behavior. I'm regaining control. When I reach my appropriate weight I'll put the pills away. I may use them on special occasions, like going to the state fair or to several restaurants during vacation. The other good news is that the undesireable symptoms have vanished for me!

I would not recommend Alli for everyone. People with digestive disorders might suffer consequences detrimental to their health. People not willing to be patient and persever through a week or two of inconvenience will not be happy. Those not willing to consider a healthier lifestyle will be wasting their time.

But for healthy people needing the impetus to get started and some initial success to build upon, this is a great way to kick things off.

Good luck!

The weight loss is due to reduction in fat. All Alli does is block a little fat.

If you don't eat much fat then what is there to really block? It's like taking your car to a "best" car wash in town, but the rules for this "best" car wash to work is to have all of the dirt already removed before you get there... make sense?

I bought Alli, regardless of the numerous responses I had read saying they saw no results.

Here's my theory....while on Alli, you're supposed to cut back on fat drastically and change your diet. Thats a good thing. If you end up cutting your fat down to under the 15 grams, you don't really need Alli.

I mean, its supposed to stop some fat absorption, but if you're down to barely any fat in your meal, its not gonna do anything for ya. I guess if you plan on still eating a ton of junk, it should help and give you the unpleasant side effects, but if you really watch your diet and cut down to barely any fat, the pill is basically useless and outrageously over priced.

I took it for a few weeks, but since I already had cut almost all the fat out of my meals, it did nothing. Just nothing. I was so disappointed that I had spent over $60 for something that didn't do anything beyond my own change of diet.

I did like that it came with the support website, but overall I was frustrated. I had taken another type of diet pill previously and had lost 20lbs before my wedding in about 2 months time. After the wedding I gained a few back, so I though I'd try Alli.

Needless to say, Im switching back to the old stuff because it helped. What I really need is something with an ingredient that will help control my hunger, and Alli doesn't have it. So im miserable struggling not to eat as much, but still so hungry.

On the other pill, it helped me to feel full longer and not hungry. It also gave me the energy i needed to work out.

How long have you taken the product? I took it for a week

Were you dieting in addition to taking the product?

Yes, it is required; in fact, I did a week flush staying away from fattening foods the week prior.

Were you exercising in addition to taking the product?

Yes, I was every day. I had already lost 8pds naturally and only wanted Alli to boost the weight loss.

What do you like about the product?

The product was over the counter and FDA approved. It has a lot of information, attractive packaging, and a portable case with tips.

What do you dislike about the product?

I followed the strict guidelines and the first two days were great after that I had bathroom troubles, severe tummy pains. I was unable to continue the program, which is expensive.

I have tried other pills with scary results vomiting for hours or caffeine high and the only reason I gave one more brand a try was because of the FDA stamp. I hoped it would be safe and effective.

I am done with attempting pills. The old-fashioned way is tried and true -- more work but safer. Please don’t waste your money on Alli or any other pill.

I've known for a while that their is no "magical-pill" out there that makes you lose weight. I'm also under the impression that absolutely none of the diet pills out their really do anything other than cost us money.

The big catch for me has always been the "This product has not been evaluated by the US Food and Drug Administration. These products are not intended to..."

Seriously, anybody in their right mind can pretty much make up some phony diet pill that "guarantees pounds of fat to be lost."

The one thing that caught my eye with Alli is that it is the only FDA approved weight loss aid available in the USA. Not only that, but it is based upon Orlistat.

So, I buy a bottle, read the directions a few times, and tried it out. I changed my diet up, as it suggests, by eating three meals a day under 10 grams of fat per serving.

Before I say the results, I just want to mention that I have NEVER lost weight before with any diet pill on the market. Oh, and I guess i should mention my dimensions, too. I'm 5' 9", male, and 170 lbs.

So I follow Alli's directions to the T for about 3 weeks. I weighed myself on the first day, and lost about a pound. I thought nothing of it. By the end of the week, I was up to 3 pounds. The middle of the next week I had lost 6 pounds. This shocked me. A diet where just about everyday you lose weight.

I ended up losing about 9 pounds in 3 weeks. I was pretty impressed, felt better, and actually showed a slightly slimmer waist line. But as Alli's label suggests, users who get off the diet will probably gain the weight back, and then some. And thats exactly what I did.

This diet leaves you pretty much feeling starving all the time. I mean, 10g of fat per meal, 3X a day is a pretty tiny meal. In a way I went fast food crazy, and started eating all that junk again. Not only did I gain the weight back, but I tacked on about 10 extra pounds. I will say once I get the mental mindset of determination, I will be taking Alli again.

For me, it worked. You just have to stay with it, and follow your diet exactly. I'm sure I need to look into finding a few good fat-free and reduced calorie foods to snack on. Oh, and for those "negative" side effects everyone talks about, if you follow the diet as suggested, you will not run into any problems.

If you're the typical obese American who wants to munch down big mac's while taking diet pills, you will experience them. And I will be implementing exercise into this diet as well. Bottom line, Alli works. Again, the ONLY FDA approved weight loss aid, PERIOD.
