I have tried Welbutirin, with horrendous anxiety and insomnia side effects. Had the same reaction to zoloft and paxil plus sexual side effects. Then tried remeron which was good for the first 6 or 8 weeks and I slept great but then the anxiety and libido took a crap.I have Neurontin prescribed for back and nerve pain that I sort of disregarded and only took for a short while. If Dr. okays how long have you all found that it takes for the gabapentin to start helping with depression /anxiety issues? Thanks in advance to anyone who takes the time to answer it's been a very tough road really hoping to get on the right rack.
