I have taken prozac flunil 40 for 2 months and then flunil 20 for next 10 days (because I had ed caused by depression). I felt sexual side effects in this period. After discontinuation on 10 august (about 10 days, now also I can't get my sexual desire back and erection. So I want to know what is the minimum no of days required to get rid of this effects and getting back my desire after the discontinuation of this medicine.
