The side effect is that after eating, I feel that I can't eat anything else but drink water. Sometimes I feel sick even drinking water, and I feel full every day. After a long time, if I like this feeling of not eating, I will lose sleep. I'd better eat during the day and can't sleep after three in the middle of the night. Then I continued to watch TV. Hahaha, I lost 12 pounds after eating seven tablets, and the effect is very good. After half a month, my appetite recovered and I gained weight.
