Wednesday Weigh in

If I go by what I weighed this morning 220.5 I have only gained a 1/2 a pound over Thanksgiving which I believe is a blessing.
If I go by what I weighed last night I am 219.

How can I gain 1.5 lbs over night????? Oh well on with the show as they say. It is grey and gloomy today so I think I will take DD#2 to Wal-mart and walk around the store, working on my steps goal.
