I know it's so bad for your teeth, but I LOVE eating ice these days. In the last couple months I guess you could say I've been craving ice, but I wouldn't necessarily consider it a food craving. It's weird, but I now know which restaurants have the best ice cubes. The winner is A&W :-) It's like little rods of ice that have been broken into smaller bits. Also it's not so hard as normal ice cubes, so...maybe not so hard on my teeth?
