It's only happened twice. I'm afraid to jinx this by saying anything, but I feel I have just walked into heaven when I got on Viibryd. To be on an anti-depressant AND get to keep my sex drive AND actually be able to achieve orgasm MORE frequently and easily than before? I hope nothing goes wrong with this drug, as I hope to be friends for life with Viibryd. I'm looking into buying stock in this company.
