1.9 lbs is great, Barb! I wouldn't assume it's all water weight. I lost .5 of a pound this week, and since I also lost last week and a miniscule amount the week before, I'm going to tell myself it's real. :-) And you're right, just eating less seems to be the reason, for me. My only normal-sized meal of the day any more is lunch.
By contrast to Florida, here it's about day 70 of no rain, and none in the forecast either.
