anxiety
"Battled with anxiety and depression for almost 30 years now.  Was on Xanax but got addicted to it and ended up in hospital recently.  Tapered me off the Xanax and gave me Gabapentin 600mgs twice a day.  Started seeing a difference in a few days, amazing.  Works better on my anxiety than any benzo that I have been on.  And I have been on most of them at one point or another.  I wake up in a good mood.  The only drawback that I have is that the morning dose makes me sleepy til about 11an but that is it.  But I am not complaining because I would rather be sleepy than anxious and depressed."
