"after many antidepressant medications over the years, i had resigned myself to a low sex drive and a bit of flatness in effect. but after viibryd, i regained that sexual spark and the depression lifted. it&#039;s been 4 months now and i&#039;m on 40mg having stayed two weeks at 10, two weeks at 20, then 1 week of 20, alternated with 40 mgs. and then finally one 40mg daily. i have struggled with sluggish bowels for years so this may be why i didn&#039;t have diarrhea. however, there was some gasiness the first month and bowels more loose. no nausea but i do take it with a spoonful of peanut butter. most days i feel content which for me is exceptional."
