I agree with Jasmin Song's review. This is not a miracle pill, it basically suppresses your appetite, like it does for me, especially during premenstrual mega cravings!=( So combined with a sensible diet and excercise regimen it does help. This is what actually makes you lose the weight. The one thing I don't do is take it daily, I don't like relying on supplements to control my hunger or craving cycles. I only use it as needed.
To the other reviewer who's using this with Dexatrim to crash diet, just warning you that drastic measures like what you're doing never work in the long run. It's a sure fire way to yo-yo dieting. But hey, if it works for you, great. It's maintaining that weight loss after that's tough. Believe me I've been there a few times.
