En bloc blackout

Hi. I experienced my first (and last, im never drinking again 😭) en bloc blackout after drinking 10-15 mimosas on an empty stomach. (Do not ask why. I just kept asking for refills bc I was feeling great till I stopped feeling everything smh). And yeah was up for like >2-3 hrs with no memory! (Also ik what happened now cuz thankfully I wasnt alone but omg !! Like fr never drinking again I never need to risk this experience again but please if anyone has more information on just this process and HOW I was awake and mildly functioning during this ??? But with 0 recollection even after being told please and dont tell me to google it I HAVE been I need more info cuz what just happened to my body is this a sign of a future neuro compromise and okay let me go before the hypochondriac takes the mic

Tyyy in advance
