I am a certified ice cream junkie.
I can, for example, eat a half gallon in day, easily. One bowl at a time, especially if I am watching something on TV.
I used to be horrible with candy and chips, but I am better with that now.
I monitor what I buy, but I have to allow some snacks and goodies for the kids. I just don't buy ice cream anymore. Ever.
Complication makes it easy to explain failure.
