Ditto Lily and others.
Not to be mean, because I’m in the same boat as you, so this applies to me also, but the mentality of “Just a little cheat won’t hurt” is what got us here, know what I mean? I’ve said that my whole life, which is why I find myself now almost 100 pounds above my goal weight!
You CAN do it, just stick to the plan, and don’t cheat. If you need to, ask them to make a low-carb jello fluff with sugar free jello and cream cheese. They can. Like Lily said, they pretty much make whatever you ask as long as it’s fairly reasonable.
