I found taking a bath helps for the same reason. . . humidity, plus if I half lay down it helps relax tension.
And the weather-change thing is NOT hokey at all.
I've heard of doctors recommending Gatorade if you're having a hard time drinking water. I tried that, and for some reason, that didn't make me as nauseous as plain water.
