I can't believe this. I took Propecia before, got gyno stopped. Then, i think maybe i'll take .25 mg of propecia EOD and after 3 doses, yes 3 = .75mg total my nipples are sensitive and are swollen. What the hell. I'm going to a pool party weekend in 16 days but now i have gyno. Does anyone know how long it will last?? keep in mind, i took 3 .25 mg doses. That's less than 1 pill total over a week span. Come on!!!! the sad part is, my hair was shedding before that's why i took it.....and when i started took it last week, my hair immediately stopped shedding. unreal. i'm soooooo sensitive, guess i'll be rogaine.
