I was able to try an experimental ketamine treatment in the hospital.
3 doses administered via IV every-other day. (Monday, Wednesday, Friday)
The first and third were failures for me. Nurses talking in the OR completely distracted me and "stole" my awareness.
But the second one was perfect. I was able to feel nothing. I was able to shut off my mind and enjoy the single most peaceful moment of my life.
As time & work permit I plan on doing this again. Especially now that I know I need to be blindfolded and have ear-plugs in. (this sounds dramatic, but it's what works for me)
It hasn't cured my depression, but it has given me hope. And that's more then I have ever had.
