"Tuesday, February 2, 2011, 12:30 p.m. Wife is passed out on living room floor"
Do this and slowly build your case. Start stashing important paperwork elsewhere (like a safety deposit box at the bank, or in a locked cabinet at work), just in case you'll need it later on.
If you are considering separating, you will need documentation and legal representation, no matter how crummy the legal system is. Heck, navigating the system can't be worse than the rollercoaster ride you're on now...
Very good advice, and also might make you FEEL better about your situation knowing you are preparing yourself with a back up exit plan. I've been saving money for months now - for a down payment on my own house - or a bigger house for me and my RAH. Either way, I will be ready. It's amazingly liberating and also helps mentally deflect the crap that they say to us.
Take care of those kids - they need you.
