Gabapentin
"I was put on this this for Diabetic nerve pain.  The starting dose was 300mg twice a day. On the starting dose, I found I was slightly moody, had some stomach problems and the nerve pain was just as bad as ever, if not continuing to get worse. My Dr raised the dose to 600 twice a day and I became someone I did not even know. I was extremely moody, angry, difficult to be around. HORRID! It also effected my stomach more. I would eat, even just a small amount and have stomach pain, vomiting and so on. It got so bad I simply stopped eating. I simply lost the desire to eat, despite feeling hungry. Started having trouble with vision and intense headaches as well. 



There has to be another option. I can't live like this."
