Need advice on how to relapse

Just to clarify, alcohol isn’t my problem. My problem is meth.

I’ve been sober for around a year and I just moved to the phase of the program where they don’t breathalyze you anymore, I’m basically living alone with the occasional drug test. I really want to get fucked up for like $25 max. What type of alcohol should I buy, and how much of it would I need to drink to get positively sloshed? I’m like an alcohol virgin, at least when it comes to getting super fucked up on it, so any advice is welcome!

I’m like 230 pounds

Cheers
