Get a smooth cocktail with vodka.
Vodka doesn't really taste like anything, so it'll only be the flavor of whatever they mix in the cocktail.
Since it'll be your first time drinking, you'll probably hate the taste of alcohol with all sorts of drinks you could have it with, because it's a fair bit bitter.
I'd suggest some cocktails, but I'm too damn tired to think of any right now.
I'm also trying not to think of drinking so that I can avoid drinking.
