Im goin to venture a guess and say your experiencing the symptoms that got you prescribed cymbalta in the first place?
Your best bet would be to analyse your life as honestly as you can, figure out what time of day, location, food, anything that makes you on edge. Then figure out how to limit your exposure to these things.
Meditation, and stretching work wonders too. It clears you mind, leaving you extremely relaxed during, and afterwards.
This is the first time you've been exposed to your senses in an unfiltered way in over a year, you now have to figure out how to cope with that.
