I don't drink from a sippy cup

But anyway, it just gets nasty for me when I get down to the bottom of the jug and it's like an orange juice stew. I suppose it's a matter of personal preference, to each his own.
Nothing like a tall cold glass of Tropicana after a long hot day swimming. (and my doctor says that a bunch of the calcium that I eat I lose in my urine, so that's why I have the calcium version!).
