Sooooo, I did decide that, on my scale, I weighed 202.5 this morning - *a new low for me* if I was right. I decided that, hopefully tomorrow there will be less uncertainty in the reading.
I weighed myself at the Y on one of their accurate scales and got a reading of 210 (including the 10-12 ounces of water I had drunk.) At 5'9 1/2", 209.5 pounds is, that's a BMI of 30.5, meaning that I'm overweight at home and obese at the Y. I can handle this discrepancy, but it has occurred to me that I really do want to be under 200 pounds, even at the Y. I'm not going to change my goal of 198 (here at home) but I'm realizing that that's going to be just sort of a Part 1, with Part 2 meaning I have to get to 198 at the Y. Apparently that'll mean I'll have to lose another 6 pounds or so after I reach goal Part 1 before I can honestly say that I'm really under 200 pounds.
