I'm at my wit's end with trying to lose weight and am looking for an effective diet pill.

Before you even think about taking this medication, go to the website and read the side effects. Alli blocks the absorbtion of some of the fat you consume. If your body doesn't absorb it, the only way for it to come out is in your stool. Alli causes loose stools, frequent and urgent need to go poop, and oily anal leakage. The website even reccomends bringing a change of clothes with you to work. There are so many other ways to lose weight....why go through all that?

My mother is on it right now and doing good so far.

You don't need a diet pill. I lost 50 pounds ALL NATURAL. Join a weight loss club like Weight Watchers or Jenny Craig. If you DO lose weight on diet pills, you will gain it back SO much quicker if you go back to your old eating habits.
Good luck

Alli stops your body from absorbing a portion of your fat intake. It absolutely does that. And the side effects (anal leakage) will keep you from eating fatty foods. It's a great pill in combination with a exercise program.
