Pondering

I wonder when everybody else weighs themselves. I mean I usually weigh myself at night because I am NOT a morning person. But lately here this past weekend and the last couple of days I've checked in the morning. There is about a three to four pound difference. I know that it's fluid that my body is holding onto from my activities during the day, but which one is considered more accurate? If I could be the weight that I am in the morning then WOOOO! But that wouldn't be accurate compared to my beginning weight. I don't know what I weighed that morning that I went to the doctor, so perhaps I'll stick with the evening weigh.
