I'll throw in my 2¢. My take on ketamine is this...the earlier you have it the better results can be achieved but not for everyone but for many more who waited too long. If one gets relief from the infusions, yes, cut down the meds if not, well, the pain would still need to be controlled. There are also different ketamine infusions----single injections, 4,5,10 day infusions lasting different amount of hours each day and apparently different methods of combinations of ketamine and other drugs. And the Coma infusions done in Germany and Mexico.
