I feel the same way about keeping weight off. When I hit my goal, I always feel fantastic for a few weeks, then it slowly but surely creeps back on. Part of my problem is that I simply hate veggies. So I can't force myself to eat them. I really need to focus on portion control, which is a pretty similar problem I had to drinking too much (can never stop after I've started eating until I've finished everything in front of me).
My cravings this week, unlike last week, are non-existent, but this party on the upcoming weekend is causing me a ton of angst. My AV keeps saying that it's Ok to drink just one night. Ugh
