Because I also see a 2-3 lb. weight gain the WEEK of my TOM it does get very discouraging even though intellectually we all know it is just water weight. Drinking extra water doesn't necessarily work for me - I just have to wait it out...
One thing I want to caution you about, though - because the scale says I weigh more, and I feel bloated and blah - I find myself not really wanting to eat (this is during - not before! I chow down then!) Make sure you eat!! You can bring on a stall by not eating enough.
Just try not to worry about it, keep telling yourself that you're doing fine, eat, and eventually the scale will reflect that, too.
