The idea of using artificial sweeteners is pretty cool. My first thought would have been using urea too, but didn't know it also came from sweat. Two more interesting chemistry points: (1) quite a bit of a surprise that the smell of pool actually comes from trichloramine (side product of urine + chlorine). So whenever that smell is strong, the pool has higher concentration of pee.. (2) Urine is free of bacteria and that makes drinking it sick-free (although quite gross)
