Hey. Im 18 yrs old, and i really have to lose weight to p the weigh in.?

Im in the National Guard, and have went a little over board since in finished my BCT. I still have to go to AIT. I have been dieting, and working out, but im not shedding any weight. I have stopped drinking sodas, no ice cream, no candy, and have been watching my calories. I am hypoglycemic, and have to eat Pnuter everyday to regulate my sugar. My friend is taking hydroxycut hardcorps while working out and dieting. He is shedding weight at a decent pace. Not as much as the bottle says he would, but he is also being responsible about it. He suggests that i try it, but the effects might be different with me being smaller than him. I have also seen adds for Acci berry i think, and Lypo Fuze. Anyone have any suggestions?
