Ordered AIFM and still debating on fat burner. Is Thermowhatever the only one they have or do they have others that work well? I saw they had some other stuff, I don't like feeling jittery and ephedrine did that to me. Any suggestions? I have to get this weight off. I'm in my early 20's for pete's sake, I don't need this. I have been doing cardio and dieting, but it's not coming off fast enough for me.
