Lol. Ten years, and you're starting late. You'll end up fasting because you won't be able to keep an income, and you'll end up seriously addicted so you won't be choosing food. So don't worry about that.
If you can handle the hallucinations, tremors, seizures, then you can expect to tolerate that for about five years. It will take you five years to get there and five more years to die.
And you get no time to acclimatise to drinking. You start tomorrow morning by drinking spirits straight out of the bottle. You won't be able to get enough into your body to really count toward your death by drinking, because you currently lack tolerance. So you better get to work
