Drinking everyday for the last 2 years. Quit 3 weeks ago but no urges.. Why?

I was drinking pretty heavily for the last couple of years. Every night i would get to the stage where i stumbled to the shower to wash off the day’s work, wake up, feel like shit, go to work, come home and do it all over again.

Recently i have started to take a look at my weight and realise that something needs to change so started eating and drink healthily.

I for sure thought i would need to wean myself off alcohol because i thought i was addicted but 1 first day without it came and went so i waited till the next day and nothing also. It’s been 3 weeks now and i have no withdrawals from it at all and i don’t understand why.

I’m naturally a curious person and this is very much not a brag to anyone trying to quit. I’m just trying to understand why i’m the lucky one, i don’t get it…
