Straight water doesn't make me sick, but unless I'm already pretty thirsty (working hard/exercising outside in summer) and it's full of ice, I find drinking water unpleasant.
I'll drink water when I have to, but I'll drink flavored/calorie free drinks because I enjoy them, thus staying far more hydrated.

I'm bad about remembering.
Then again, I suspect I somehow may have ended up with the good gene as I have incredibly dry ear wax. On top of that I typically use antiperspirant instead of deodorant anyway, because I dislike feeling wet.
