actually you might be joking, but opiates are certainly an intervention for those on suicide watch.
the problem with opiates is that they require higher and higher doses, and eventually the doses are so massive that it manifests as psychotic symptoms and the come down/detox is horrendous.
buprenorphine is another intervention type drug..but despite the documented mild comedown, it is still hell on earth..dont let anyone tell you it aint.
still, for those where nothing else works, these at least give some life.
alcohol is another story as its a nasty depressant...you should not use it even for intervention..if you want tio kill yourself now, you'll porobably do it after leaning on alcohol for self medication purposes...
also, this crap in this thread about one AD being better than another, and AA's being superior to ADs, and SSRIs> SNRIs,and MAOIs,and tricylclics and so on, is, well, complete crap.
the problem is that noone has mapped the brain well enough to be able to work out exactly how these things work- which is why some people can and others cant be fixed...no one really knows..maybe in 100 years when we've mapped it a little better..
no one mentioned deep brain or vagus nerve stimulation..apparently DBS give immediate and marked relief to those in despair...they effectively turn off, or turn on parts of the brain...its the modern form of removing chunks of brain tissue.
