I think Lisa threw her computer out the window!
Molly, your body will get used to the increased amount of water you're drinking and you won't be peeing soo much soon! Right now I'm drinking 4-5 .5 liter bottles a day while at work, plus a few 20 oz. glasses at home and I'm not floating away yet!
Chris, You've done a great job soo far! Have you tried adjusting the amount of calories you're taking in? I dunno, maybe try a few less? How about exercise? What kind are you doing? I can't even imagine how hard it must be to go to school f/t, plus raise 3 girls!!

Well, actually, I guess it's not that much different than working f/t, except that you have homework/projects on top of it all, huh? Maybe you can just get lots of exercise while enjoying playing with the girls?
