I've read a few good reviews on the internet about, and it sounds like one that might help me (I have massive hunger all the time, gain lots of weight if I eat anything over 1000 calories a day, have over 100 lbs to loose).

Sorry to change the subject, but if you gain on anything over 1000 calories, with 100 lbs to lose, you could have a thyroid problem, you probably should get that checked.
