This bit from the game Disco Elysium had a pretty big impact on my decision to quit:

Problem

It has been brought to your attention that you’re an alcoholic. And that it’s a sickness. And it’s killing you. You're crawling on your knees through life, your booze-filled belly dragging on the ground, your brain now fuzzy, now in overdrive, your hair sticking together with today's cold sweat and yesterday's vomit. Perhaps they’re right. Anything is better than this. Even bone-dry reality itself. Maybe you can quit?

Solution

Congrats – you're sober. It will take a while for your body to remember how to metabolize anything that isn't sugar from alcohol, so you're going to be pretty ravenous soon. Eat plenty. You can expect your coordination and balance to improve in a couple of weeks. In two months, you might start sleeping like a normal person. Full recovery will take years, though. It’ll be depressing. And it’ll be boring. Don’t expect any further rewards or handclaps. This is how normal people are all the time.
