Cyproheptadine
"I am 5'7" weigh 109lbs and had three kids over 8lbs. I am anorexic and had been doing everything to maintain a healthy weight. When I started taking Periactin (cyproheptadine), I was gaining 1-2 lbs a day. The only problem is that 3/4 of my day I was sleeping, had dry mouth and very bad mood swings. Due to my heavy work schedule it was hard to continue taking the pills. When I stopped, I lost the weight as quick as I gained it. 4 days ago I started taking it again and gained 5 lbs. This time once I reach my target weight of 130, I will set aside a meal plan to maintain this weight in addition to taking only 2 pills a week. I would highly recommend this medication to anyone who suffers from anorexia or had no appetite."
