I used to work weekends at a British ice cream parlor when I was 15-16 years old.
It was run by Italians and they made their own ice cream, and consistently won awards for the best ice cream from independent makers.
The rule was we could eat all we wanted as long as we asked first.
Along with most of the other staff, I gorged on the stuff for a short while, then lost interest. A lot of food makers had this policy, and it worked.
If you have an addiction to ice cream, perhaps gorging on it until you make yourself sick of it might work.
Claud.
