I was put on Aponortryptiline (spelling?) for chronic pain symptoms. It was severe nerve pain in my shoulder, which the medicine completely relieved. I also suffer from headaches brought on by clenching my jaw, and the medication also helped me with those. I have stayed on it for the past year because I noticed that small episodes of depression I experienced daily were also pretty much erased after I was on the pills long term. The only side affects I have noticed were drowsiness in the beginning, which was nice because I have problems sleeping, which turned into alertness after about a month of being on them. If I take them early enough in the day, it's not too bad.
