It failed to feel like anything, which was one of the weirder parts. It never felt as immediate and urgent as what I usually identify as a craving (e.g. with chocolate). I would just feel like the next thing I ought to do would be to get some ice and eat it. Rather quickly - I think over a week or two - this stopped popping up on my mental to-do list. I also got less pleasure out of eating ice, and less vague unnervedness from not having access to any.
