I drive out of my way to go to QT for ice. Then, I bring in the 54 ounce cup to fill with ice and I buy another one filled with ice and soda. My kids drink most of the soda, and I have more ice to chew. 
I just told a friend last night that I choose fast food restraunts according to what kind of ice they have. (I said it half joking, but it really is true) 
I can't go to bed at night if there is still ice left in my cup. It just has to be chewed. I can't leave a restraunt if there is ice still in my cup (or my husband's cup). I've often asked for a cup to go so I could have ice to chew on my way home. 
I have filled ice trays with small amounts of water so it would be easier to chew. I even shopped around to find smaller ice trays that would make "good chewing ice". (I was NOT successful in finding one) 
My husband jokes about knowing when ice is "soft". Truth is, I DO know the difference between hard ice and soft ice. (It's not the size of the cube, it's the consistency) 
I get aggrivated if the ice maker gets stuck and I run out of ice. I bag up the extra so that it makes ice all night so I will not run out. When we have company and have to use store bought bagged ice, I keep a bag of our homemade crushed ice and use it, because it is softer. 
Everbody jokes about it and so do I, but I really do crave ice and feel like it is an addiction.
And the list could go on and on and on. I feel like I can "come out of the closet" with my ice addiction and not feel guilty any more. What a totally funny feeling over such a seemingly small thing. But, to those of us who chew ice, we know the truth behind the addiction and the secret ways we search out the perfect ice.
I am so glad this site is here. I'm not alone anymore.
