Anyone else???

I have this uncontrollable urge lately to eat ice and more ice.I just love the crunch or whatever the only problem I am seeing is my poor teeth.I have my blood work done every 3 months and my iron levels are good.I have heard if you really like to eat ice it could be an indication of low iron.Maybe its a faze but I love the commercial ice.I was into the low carb popcicles for a while so maybe this too will pass-for my teeths sake. I think its strange-anyone else??? laura
