Sounds like a rough night, 55!
That point when you realize you've gone over the edge during a night of drinking is an awful feeling, although it sounds like you don't remember feeling that, haha.
A couple months ago I crossed that line, and after our friends left the apartment, I hugged the toilet for a long time. By the time I was able to stumble out of the bathroom and into my bed, my roommate had cleaned the entire apartment, and was just finishing up a movie
I feel like I have a pretty good handle on knowing where that line is now, thankfully.
