Gabapentin
"I was prescribed this for nerve pain in neck and back. It has helped with the pain but the unexpected mood enhancement side affect has been very welcome. I didn't realise how much of my time was taken up with negative thoughts and mild depression. I am much more focused and positive. It's like aspects of my personality that had been wittled away by the rigours of daily life have returned. I am also a  performer and have found it very calming.

After experimenting with dosages and working out the trade off between pain relif and drowsiness I found a level. 

My only side affect which I haven't noticed anyone mentioning in the reviews is that I pee more often. But I'm so laid back these days that it doesn't matter lol."
