Duloxetine
"I was put on cymbalta to combat the mood and pain problems associated with fibromyalgia. It dilated my eyes, which led to light sensitivity and headaches. I also grew steadily more and more exhausted and confused and foggy. I was depressed. The doctors insisted that the side effects would abate after about six weeks, but they were so debilitating I had to seek out disability accommodations at school and drop one of my classes. After about a month I woke up one morning feeling very strange, and a few hours later had a seizure and sprained my jaw and have had jaw pain ever since. At the emergency room, they told me that the cymbalta was the likely culprit. Essentially, this drug made my life unbearable."
