If anyone has any suggestions to deal with this, I'll try them.
If you’re craving soda, I suggest this brand:

Low sugar, and roughly 25 calories per can. It’s not as sweet as regular soda, but if you need something fizzy and sweet, it’s a good compromise
If you want something that’s cold and chocolatey, I suggest this:

You should obviously be mindful of how many calories are in it (90 per serving). Also, it has some fiber and fat in it to keep satiated
If you really need ice cream, I suggest this:

Due to the nature of being a bar, you’ll be more aware of how much you’re eating at once. The issue with pint ice cream is that it typically has 2.5 servings per container, so you can end up easily getting 900 calories of ice cream out of a single pint without thinking about it
Obviously, sometimes you just need the real deal, and that isn’t bad, but going for lower calorie and lower sugar treats for a while instead can help you savor the times you do get the very sugary treats.
