Weigh yourself daily?

[lph]

(unlike most of y'all I'm heavier in the mornings - and when I've gained 4 lbs overnight I can be sure it's bloating!)

I hope I don't sound snarky, but how is this possible? Doesn't it violate some law of physics? (I should know which one but it's been too long. My deepest apologies to sir Isaac.)

I can see your stomach swelling overnight (well, not literally, but you know what I mean) but not your weight actually increasing.

But I don't have a scale, so I don't really have a clue how my weight fluctuates daily. I weigh myself when I'm at the pool once a week or so and can usually guess my weight accurately within a pound. Except for that beached whale thing I do once a month.
