I gave up alcohol when I realised both parents were functioning (at the time, Mother fairly rapidly became non-functioning) alcoholics, and that I was becoming dependent on it to have a good time.
That was over 20 years ago - I can have the odd Baileys at christmas but I rarely do as half a glass makes me feel pretty horrible, I do not like feeling the effects of alcohol at all now.
My mother died of it - seizure related to alcohol, she had one, survived it, denied absolutely the truth of what it was the second she got out of hospital. 9 months later she had another and this time we didn't find her for 3 days, instead of 3 or 4 hours. She was alive when we found her, but barely - on her bedroom floor. Had to get the police to kick in the doors, she passed in hospital the following morning having never regained conciousness.
Unfortunately, threads like this won't shock someone into stopping, because they believe it won't happen to them, these are things that happen to other people. They have to really fear it WILL happen to them, and believe it, and actively want to change.
Sadly, my mother did not want to change, told us we were all ridiculous for being concerned, wanting her to stop, we were all outrageous fantasists...she didn't have a problem, didn't drink at all and had no idea why there were sherry and vodka bottles hidden under the mattress and down the side of the bed... We must have hidden them there (she lived alone, we rarely went into her house as she wouldn't let us!).
I am sorry you've had to experience that @twiddlingthumbs69 it is traumatic, please please do seek some counselling/support if you haven't already.
