My own personal obsession with the cold stuff is driven in large part by habit. I don't have an iron deficiency, anemia, or teeth fractures (I was checked). My habit started 2 years ago when I was going through a stressful time. Now, years later, I still crave at least 3 cups of ice per day and for no apparent health-related reason. What's my problem?
Although I eventually plan to confront my addiction, in the meantime, let me offer a helpful hint on scoring ice. Most convenience stores won't charge you to refill a previously purchased glass. If they do, its usually a nominal fee like 25 cents. Of all the common addictions, at least our habit is cheap!
