I ve been chewing ice lately. I ve never in 43 years, I know it s terrible for my teeth , yet I find some weird type of great relief/ sensation when doing so. Almost as if, I was smoking a cigarette, in which I don t smoke . But I crave it now. I have had an extreme amount of stress introduced to me 3 months ago, then soon, came the ice chewing. I ve also quit drinking alcohol, Are they all related?
