depression
"I took Cymbalta for about 6 months for clinical depression. Although it helped the depression a lot, I couldn't stand the side effects. I lost about 20 lbs (I'm already underweight), I started having almost constant migraines, and all I wanted to do was sleep.  It was hard to get through work because I was so tired.  Then on my days off, I would only wake up to make dinner for my husband, then I'd be back in bed."
