Seriously though, the pills and alcohol are old hat; but, what do your VA docs have to say about the blackouts?
Has the VA crisis intervention hotline been of any help either to you directly; or, in motivating your docs to try different approaches?
I'm sure you already know that before you suck on the barrel you first have to squeeze lime juice on it and sprinkle it with salt. Doing that to a good barrel should alone be enough to make you try all other alternatives first.
You can do it; but, you don't have to do it ... it's up to you.
