"by week 5 on 40 mg, i went through the typical nausea, it all went away nicely after week 3 or so. then came the arm jerks. only happened a couple of times, enough to wake me up, doc said to keep on the viibryd. next day had a headache, no big deal though, and a couple of days went by after that without problems. then, the titanic crashed. i&#039;d be lying down ready to go to sleep and my head would zap like a cattle prod was put to my forehead. imagine being zapped every time you try to go to sleep? i could not get off this fast enough.
