I don't want to put a downer on your expectations, but I'm not sure these pills help at all

There MAY be some people whose metabolism reacts to them in a good way, but I've yet to meet them, so cutting down on food/eating more healthily is probably a lot more helpful. And "exercising" doesn't mean you have to go to the gym - I'm quite happy doing 30 minutes on my Wii every morning, and taking a walk whenever I can, or dance away the evening... good luck!
