I'm on finasteride for almost 5 years, dick is working fine, everything is working fine. I thought finasteride would cause some sides but no. Then I took Prozac for a week and I thought I was in hell. Not saying that Finasteride doesn't have sides, it does as it affects prostate size, but the sides are WAY WAY WAY overblown compared to how many people take SSRi's and don't bitch about the side effects of them. And I developed plenty of them from dry mouth, vertigo, anorgasmia, intrusive thoughts, brain fog, tremors and convulsions.
