I have not had an alcoholic drink for more than three years right now and it's mostly for mental health and general...

Thank you ;)
Took me time to realise drinking like I used to was meaningless.
But hey, better late than never :)

I quit drinking overnight, which is not really recommended, because if you're deeply alcohol dependant you could going through "Delirium Tremens": a rapid onset of confusion usually caused by withdrawal from alcohol (symptoms such as shaking, confusion and hallucinations).

So take your time, do/feel it at your pace/rhythm and be safe!

I don't really care, I have been straight edge for about 7 years now, I've even cut out sodas and other sugary drinks. Only thing I drink besides water is milk, coffee and sometimes tea. I have no problem with people drinking alcohol (unless they can't control themselves and end up puking etc.)
I'm not sure but I think society would change a moderate amount if alcohol consumption was suddenly stopped.
