I know a couple of people who are the same off the cider, its bad shit. Vodka redbull is the one for me, when I go I don't even know i'm doing it and then wonder why i'm getting screamed at, its like I black out and smash stuff but feel as though i'm not pissed just buzzing. Ten cans with 4 shots in each is a bit OTT though isn't it
Try drinking something you don't like, see if it puts you off a bit. I smoke but if i'm trying to cut down a bit I smoke roleys as I can't stomach too many of them and can't be arsed making them.
