What are some good low calorie beers and liquors?

I need to lose 90 pounds because i am way too over weight, but i don't want to give up drinking either. I normally drink malt liquor and things like bacardi and jack daniels on the weekends. I am what's called a weekend alcoholic, i only drink on the weekends but when i do i drink to the point of ping out. Obviously thats something i'm working on as well, but i can only do one thing at a time and right now i'm working on my weight. I need to know what i can drink while trying to lose weight. I've heard jim beam is pretty low in calories, but what else? also what beers are low in calories but high in alcohol content...keystone light? icehouse?
