Anorexia
"I had been trying to gain weight for over twenty years, but just did not have a big enough apetite. Started taking cypoheptadine and vitamin B supplement (B1,B2,B6 and B12), I gained 30 lbs. in 6 months and the response from coworkers, family and friends were unbelievable.  Everyone said I looked great. I went from a size 3 to a size 7, and I am overjoyed."
