"i have been on cymbalta for 10 weeks now.  i started at 30 then went to 60.  i was feeling wonderful, less negative, less worried, it was great.  however the last 10 days or so i have started clenching my teeth, severe nausea, horrible dreams, weight gain and dizziness.  i don&#039;t want to go back to the way i was feeling before, however i can&#039;t continue feeling this way either!"
