Clomipramine
"Out of nowhere I started having premature ejaculation problems so a doctor prescribed anafranil. The drug definitely worked and after I stopped taking it after a couple of months my problems were gone. The drug did make me feel pretty queasy and out of it (I threw up once) but it was as if my sex life was rebooted and my body trained to orgasm later. I recommend but don't drive or do anything important while on the drug."
