To anyone who is interested
My blood test result came back, and guess what? My Hb is 7.6 (which means I'm half dead). It should be at least 11.5 (for women).
I'm convinced that this is a factor in ice eating, but I also think that it becomes a habit. I'm past caring really. It's not as if it's harmful is it? I'm sure our kidneys are in excellent condition.
