My anniversary is April 20 (our second) and I am not planning to cheat, but I think you should plan to do it and not just end up doing it. I went on vacation last week and ate and drank anything I wanted. The alcohol is what did me in, I had real beer regularly. Anyway I gained 5 lbs as of this past Sunday and as of this morning 4 of them are gone. Mostly water weight. Cheat if you want to but don't beat yourself up about it, just get right back on track!
