In the midst of all the chaos going on right now? Of course, you are going to be up. My doctor told me that when cortisol is pumping, it not only makes people hungry, it can make weight go up at least temporarily, even if we don't eat more. I guess it makes us retain fluid or something. Eat your cake and celebrate. Your child getting married does not happen every day. Cake is part of the plan today. You can get back to being more strict when everyone leaves. Mark it on your calendar and write a plan for the first day or week now, well, not right now, like before bed or after they leave or something. Just make sure you plan for success at some point.

Maybe try to go back to the beginning and what you ate your first few weeks on WW when you lost so well
for a jumpstart of losing again.
