I’m 23 and have been drinking 8-16 beers for 3 years.

I’m 23 and have have been drinking every single day for 3 years plus. Some nights only 8 beers most nights 12+ beers. Every morning I wake up sick throwing my guts up and say I’m not going to drink anymore. But by around lunch time I’m thinking about what kind of beer I’m gonna buy and the cycle starts over. How long do you think I have?
