I have stop to eat ice cube

Hey thiyagu, I would presume that since you wrote "have to" stop eating that we are talking about addictive habit  of obsessive eating of ice not just you not  looking for replacement. Going with that I would suggest first thing to check is your iron levels in blood since most people with this problem suffer for iron deficit. If that's the case just go get the iron in pills or consult a physician and your problem should solve itself, if not write down more details so I can help you out. Hope this helped.
