^^^I just thought of something to add to the comments about how deathly progressive this disease is - I, like lots of us, started considering the kind of incident you had as .... "not that big a deal." My standards kept lowering and what was acceptable behavior got way away from what that actually is.
I hurt myself a LOT physically - from countless hard core bruises to way worse stuff.....and justified it as "boy I drank a LOT!" like your OP says (to me, kinda braggy-like?) and "ha, what a funny night." BS.
Hope you take our concern and comments to heart, and from our experiences - not as criticism or judgment. All of us have to CHOOSE if/when to stop....hope you do NOW.
