I don't get it.

Once again, this morning I tipped the scale at just over 137. I don't know why my weight varies so much from one day to the next. I certainly haven't been eating mass quanitites. The only thing I did different is I had 3 glasses of Coke. That is alot for me. But would that really make the scale read that much heavier? I find that hard to believe. I am hoping to hear something soon from Drug Delivery saying that my supplies are on the way. I am anxious to just be down where I want to be again. It's only 10 pounds!
