You really scared yourself....(actually you scared ME too)! i have these little insolent thoughts myself, they flit through my brain many times during the week or when I'm in a crabby mood.
I'm going to suggest that you keep an eye on yourself and inspect yourself for lumps, bruises and bumps...I know vomiting from excess booze is common, but blacking out and vomiting are also symptoms of a concussion....(altered neurological status)....if you start vomiting again, take a trip to the doctor and tell him/her you can't remember...you may have smacked your head on something...and yes you are lucky you didn't choke.
thanks for posting and chasing those same thoughts right out of MY head.
