I know where you're coming from. But for me was almost any fruit flavor ice cream and usually a quart or more. Seriously. I'd buy it saying it will be small servings but I'd go through a 1/2 gallon in two sittings.
But really it's not a spontaneous thing. Unless your freezer grows ice cream! You have to buy it first. I think it's easier (or maybe less hard?) to be strong at the store and just avoid the ice cream section rather than having the pint at home just waiting for you to eat it.
Maybe look at what you just took in. I had to B&
Js site to look it up but a that pint had 1120 calories, 50% fat, 240mg of cholesterol, and 120g of sugar. Wowza.
