I have taken Gabapentin for quite some time. I was up to 3600 a day and am back down to 1800. The additional dose did absolutely nothing for the pain level and I was fortunate to not have any adverse reactions to Gabapentin as I know many people do. I asked my Dr about a new one on the market that is non-narcotic. It is called [ the VA"s name for it ] VENLAFAXINE. I currently take 150mg a day.
