How much ketamine can the body handle at one infusion?

I hope that this helps your understanding of Ketamine. If you look it up on line you can get a lot of information about the drug. Some good and a lot bad. I hope to talk again, Cherie

My doctor spoke to 2 surgeons and both said no way to doing the surgery. Right now due to my back pain issues I cannot work right now. I am on a disability pension through the Government of Canada. Thank god my wife understands what I am going through with my pain issues. My wife is the only reason I don't commit suicide. If I wasn't married I would most likely have killed myself.
