In response to user "excellence". Starting 3rd week of viibryd now at 40mg for 3 days. Still up and down or flat feelings. Side effects so far non existent as to 7 yrs on cymbalta... Which while being FAR from perfect in side effects ; worked for me. Don't know if I should start adding a bit of cymbalta back or keep waiting on the 40mg. Seeing doc in a week(big deal; lol... They never experience the drugs efficacy or not) ... Any opinion?
