I'll probably be bood, but I vote be careful. A plate full of pasta, some tiramisu, and wedding cake could add up to a major tummy ache which would put a damper on the evening.

Instead share a piece with your husband, enjoying a few bites. For dinner start with a large salad, then have a moderate carb dinner. You might also check out the CAD forum and book, and maybe look into following it's rules for your week surounding that day.
