Cymbalta was not for me. It was a miracle drug at first, but when it lost its effectiveness, getting off of it was miserable. I remember that my main problem was occasional brain zaps-kind of like a quick blink of electricity in my head.
I have recently had a similar experience with oxycodone. I jerked awake constantly, and never actually felt that I was sleeping. Also, my dreams were very vivid and disturbing.
I don't know if these drugs share any traits other than acting as pain killers. It was just interesting to read about a common symptom with different drugs.
