Hi Lifeartist,
Welcome to the NeuroTalk Support Groups!

I'm sorry I don't know anything about this, but just read an article in our
Health News Headlines Forum this morning.

I thought I'd post it here in case it was helpful to you.

Ketamine could help treat severe depression: research

I am not sure how you'd find a doctor who would be prescribing this,
but you could try checking out the Depression Forum at the NeuroTalk sister-site which is PsychCentral.

PsychCentral Depression

Also, the people on our RSD and CRPS Forum
have a lot of posts regarding Ketamine.

I'm not sure if they could help you with off-label prescribing though.
