Wish I could just snap my fingers, and it would fall off!

I just got back from a work conference for 2 days, and I have found that for some reason I have no self control. They fed everyone so much junk. It was awsome, but my scale says otherwise. I gained a pound in two days!!!!! Normally when I'm at home I have no problem saying no to the foods that I know I shouldn't have, but that little voice that tells me I want to loose weight more then I want the carmel cheesecake must have stayed at home. I'm almost hoping to have a boring weekend, so I can make up for this weekend. I usually weigh myself on Fridays, but I think I might wait unitl Monday. Anyway, I'm going to get working out, so I can at least be on par with last week.
