Welcome Unwound, and congratulations on two weeks!
I remember the third week being particularly difficult for me. As for tomorrow I would be sure and eat lots to stay on the full side. I used protein shakes and it took the edge off. If there's time to get to the gym for a nice workout you may consider it......very helpful for me if I'm feeling anxious or at loose ends. Stick around and post here when you can slip away during the gathering.
Best wishes to you and I look forward to seeing you around.
