I am currently on 60 mg Cymbalta and have been for over a year. It works well fo rme except that every afternoon around 5:30 I want to (and sometimes do) want to go to bed. I try to only nap for an hour but could stay in bed longer. IS THIS A COMMON SIDE EFFECT? My shrink doesnt know why this happens and has only suggested that I try taking the Rx earlier in the day. That doesnt help even taking it at 8AM. DOES ANYONE ELSE HAVE THIS PROBLEM? Note: I am also taking LAMICTAL 150mg but the problem predates my taking the Lamictal.
