anxiety
"I have been taking gabapentin for about a week now and it has literally saved my life!  I was having such incredible nervous energy that was affecting my sleep, relationships, daily routine, etc. I was having a meltdown everyday with lots of physical pain (mostly stomach).  This medicine calmed everything down and is helping me feel normal again!  Thanks to a good doctor...this really worked well. Can't say enough good things. I smiled this morning when I woke up for the first time in years!"
