I'm an alcoholic and it all started from just "casually" drinking. I wouldn't recommend drinking at all, ever.
But, hypothetically:
Get a six pack of something regular but tasty like Kona, blue moon, etc. Not sure if you like beer, but I'd cop that and a bottle of Jameson. All pretty affordable.
Now, I always found it best to kick off the session with a olde e or a colt 45, then have a couple glasses of Moscato. Once that settles, just crack open one of the beers to maintain a buzz and keep your whistle wet. Take two shots of Jameson and then chill for an hour or so. Then just work thru the beers as you finish them with shots in between.
If you start to feel sick, just smoke a little bit of weed or do a bump. The bumps make you kind of thirsty but don't drink because you'll blow your high. Once you have a good drip going, then resume the beer/shot cycle.
This also works with tequila.
Let me know if you need anymore tips. But again, I wouldn't recommend drinking.
