Gabapentin
"After 20 years of every SSRIs for depression and generalized anxiety disorder I have found that Gabapentin is the only medicine that has really helped the anxiety with the exception of Thioridizane (now withdrawn in UK). At first Seroquel seemed to help but 3 months now on Gabapentin and significantly better. Still haven't found the ideal dose (now about 2400 a day) but initial side effects have worn off. My family say that since coming off Seroquel my personality has returned to what it used to be years ago. Give it a good try, and good luck. If you post on here I do think it helps if you mention dosage (and body weight 224lbs)."
