anxiety
"I was taken off of Alprazolam, cold turkey, and given Gabapentin to help with possible withdrawal.  This was a NIGHTMARE!!! I had taken Gabapentin for a short period of time before, for Carpel Tunnel, but it gave me what I call "drunk body syndrome", and I would be off balance, bump into things, etc.  I didn't really have negative effects while taking Gabapentin this time around UNTIL I stopped taking it. No one told me to very veryyyyy gradually ween myself off. I almost immediately went back & forth between having the most severe hot flashes one could even imagine (I mean, I was sweating bullets like a mad woman), cold chills, terrible body aches, flushed face, severe anxiety. It felt like the flu. Called my Dr and went back on Alprazolam."
