ibromyalgia
"Have used Cymbalta and then Lyrica for years.  Weight gain and blurred vision were the worst side effects.  I have now been on Savella for about a month and the side effects are awful.  Constipation is the worst!  Even so bad I have been to the emergency room feeling like I was in labor.  The sweats are almost unbearable.  I also have chills and insomnia.  Headaches are now a daily occurrence. "
