Ketamine might help prevent suicide
I suffer from serious depression.  I have tried to kill myself.  It comes and goes in waves.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.
