Being bummed a bit is normal, but so is the fluctuation. I used to get upset at a 1/2 pound or two in the wrong direction. But it could just be water weight or "unprocessed food" that you've eaten that isn't through your system yet. I recently had a 6 pound gain - but I know that it was because I was sick, on antibiotics and since I didn't want anything to eat except oatmeal of chicken noodle soup - it was to be expected. This week I am down 2.5 of those pounds, and I know they will come off, plus with a few friends.

For me they key, is to remember that this is not a race.
