Yeah, some people react vastly differently to different types of alcohol. Particularly if you are mixing your drinks.
Personally, wine gets me very drunk very quickly (not a good kind of drunk) and gives me a hangover in the morning. Vodka gets me good, happy drunk, keeps me up all night feeling crap when I get home (a night-time hangover, pretty much) but after I finally get to sleep I wake up in the morning feeling awesome. Vodka is therefore my drink of choice, even though I know I'm going to pay for it when I get home
I think it's the same for quite a few people. For me, drinks like beer/cider/lager etc will affect me quickly. Wine is the worst - I feel tipsy after a glass. Vodka gets me drunk but only after quite a few. As for drinks like Malibu, they don't make any difference at all.
I know a few people like you, they can drink beer after beer after beer but as soon as they touch vodka, they are wasted.
It's fairly normal to have different tolerances for things - tequila is horrific for me. I can drink pints of cider, or loads of vodka, and I'll be fine. Add one or two shots of cider, and I'm so drunk I can't even see (as I found out at my work's Christmas do - very embarrassing!)
