Has anyone tried Ketamine?

Hello everyone, I actually do not suffer from PFS, but I have read the articles that are out there and I really sympathize with all of you.

One thing that I was thinking was, and hear me out here, that there seems to be a lot of an emotional aspect to the issues you guys face. I really believe being in a poor emotional state can also manifest itself with physical symptoms like the ones you guys mention. I’ll go right out and say it: has anyone ever tried using Ketamine? There are numerous studies about it’s therapeutic use, and at this point I feel like if anyone has a feeling that some of their symptoms are more mental than physical (I’m not trying to downplay physical symptoms here), why not give it a try?
