i went through every med. in the book pretty much. ms cotin seemed to help a lot in the beginning. i've been taking ketamine orally for 3+ years now. started at 20mg/mL 2-3 mL every 2 hours. then just about 4 months ago it got increased to 50mg/mL. I haven't had to take it much the last year due to the ketamine infusions i've recieved. from 2 infusions i was in remission for 6-7 months total, no pain, no medication...
