Weird Cravings

Not a pregnancy related post, but I can always tell when I'm about to get sick because I start to crave beer. I don't even like beer, but if I drink it when the craving hits, I don't get sick or I don't get nearly as sick. If I ignore the craving, I get sick as hell. It never fails. 
Does anyone else get weird cravings that are health/event related?
