obesity
"I'm 27, 5'1 and my starting weight was 198. I started it last year (2015) in January, followed exactly what your suppose to do, and I was miserable. Headaches, tired all the time, but I figure it was worth it because after 4 months I had lost over 30lbs. Eventually I couldn't handle it anymore so I stopped taking them. 
Now I started back up again, I'm on my third week and am still on 1 pill in the morning. Its working out great for me. I'm still losing a ton, but without any of the side effects, I drink a ton of water so I wont get the headaches and my energy level is great! I think that when I do plateau, I'll up my dose, which I shouldn't get any side effects because I've been taking the 1 pill long enough that my body is use to it."
