Lance and the kids are joining me in this (thankfully, because watching Lance eat cookies would make it much harder). The kids can have a few cheats. If it's someone's birthday at school, they can still eat the treat. If they are at an activity and the snack served is something I'd consider a treat (fruit snacks, etc), they can still have it. But they've been pretty good about it, too.
I find myself reaching for fruit or yogurt when I want something sweet. I feel like I have a touch more patience and energy (though I feel that's possibly due to the fact that we've been defying winter here for quite a while now) and I'm pretty sure I can get through the month without cheating.
