i had i guess a not low dose, and not a coma, so medium dose? idk, but i had one in december and was in full remission for 2 months, i just had another about 6 weeks ago and again have been put back into remission. i had the infusion for 4 hours, the first time i had about 1500 mg of ketamine, and the second time i had 2000 mg of ketamine. i have a slight tolerance to it since i took it for over 2 years as my main pain med. i had it done in LA by Dr. Thomas Leverone. its outpatient so as soon as you're coherant enough you can leave. you're pretty much sleeping for 4 hours. he does it a few different ways, where you come in for the infusion for various numbers of days in a row to try to increase the amount of time ur in remission... he has had very good results with his methods and is a super nice doctor
