Yes I was given oxygen during the treatments. Pain paitients who have been getting ketamine infusions longer than people have for depression, are given bigger doses over a longer time. Most of these people tend to hallucinate and are given drugs to abate this.

Also, Ketamine has been proven to repair the brain. Unlike ECT, given in supervised settings, destroys brain tissue. I have permanent brain damage from
Bilateral ECTS..

Again, the take away is not Ketamine but the revolutionary research it spurred. The new drug AZD6765 based on ketamine and in phase 3 clinical trials, does not cause hallucination.

Think of this when comparing ketamine given in an infusion for depression under supervision to someone doing 'special K' on the street...... THe therapeutic dose of lithium can sometimes be very close to to a toxic level which can be deadly.
I have been in the hospital with people who taking their so called normal dose of lithium, for whatever reason, became toxic and very very sick.

I have been researching ketamine for 5 years. When I worked I helped in medical research as system/analyst computer programmer. I am not talking out my arse.
