... the exact amount off hand) and I realized that it had completely stopped my ability to orgasm. As soon as I realized this, I stopped it (which was a horrible idea I know) I had severe withdrawal symptoms for about a month. It has now been about two full months since I stopped taking the Prozac and I still can't orgasm. Do I still have Prozac in my body; how long until I can orgasm again?! Please help :(
