What is the most efficient by cost method of getting drunk?

I live in SC in the U.S, I don’t have a ton of spending money especially for things like drinks. What one thing should I get that will last the longest while costing the least? Normally I just get a 1.75ml of Smirnoff and call it a day since that is around 20-25. I was thinking about getting some everclear instead as I can get 1.75 for around 30 or 750ml for like 20. Obviously I am aware the everclear would need to be heavily diluted like a single shot in a can of coke or something but is it the most efficient? I have a fairly high natural tolerance(I guess it’s my Slavic genes) so I need like 6 or more shots of Smirnoff to actually be drunk. Is there a better option for the price, and is everclear actually worth it when dissolved? With my amount of money taste doesn’t matter a ton unless everclear still tastes like gasoline when heavily diluted.
