Ketamine therapy for ocd?

I have the compulsion to cut my hair. Had it since i was 3 im 46 now. It is NEVER even. I have in the last 2 mos cut 12 inches off my hair and theres not even enough left for a ponytail. It went away for a long time and is back with a vengeance. I recently found out theres a word for someone like me and its an ocd issue. I also found that they are treating ocd with ketamine. the fda has recently approved it. Has anyone done this and if so has it worked???
