well i already took it, and i found a vit c pill and i crushed that up and drank it an hour before the test, and my piss was pretty clear with a hint of yellow and the very hot nurse their said "you are very well hydrated" which could mean its hydrated but not to hydrated, she didnt say it was too clear or anything so i dunno, i took 4niacin 8asprin and a vit c pill and drank like 2nanglenes and a dr. pepper and drank some water out of some water fountains. btw to drink all this water and fully prepare i had to skip school of course :hippy:
