I so agree with you Ada...If the first treatment doesn't work, then why keep continuing...Ketamine is a very dangerous drug, but I am starting to consider the infusions, pill or injections. Being placed in a coma is completely scary to me, especially watching people come out of it, if in fact they ever do. Ketamine can cause permanent brain damage, if used extensively and I do think that Dr. S has to be getting some kind of kick back....for those who have been put under, congrats, but the majority of stories that I have researched have not been so positive.
