A Call Made Too Soon?

Maybe the curse wasn't broken, just bent a little. I can't explain it. I'm up about a pound and a half today (1.4). I ate out last night but I really was very well behaved considering it was an all-you-can-eat buffet. I had a small serving of pot roast (may 2 oz of meat), about 1/2-3/4 a cup of brown rice, and salad (about 2 cups) with peas, peppers and a scant amount of no-fat dressing. I also had about 1/4 cup of red beets. My only guess (and hope) is that the weight is water from the extra salt (in both the pot roast and the beets). If that's the case, it should come off fairly easy. I'll drink extra H2O to try and help today. If it's not that, I'm clueless (no comments from the peanut gallery, please).
