*New* to urine theorpy hope someone can help me get on the right foot with very clean healthy urine...

I'm doing this as a Science experiment to see how long i would be able to live on a certian ammount of water i intake and how long it would last without getting dehydrated or feel sick...I know urine theorpy is a healthy choice but Im really intresteded in how long i can survive on a good ammount a healthy urine w/o presperating at all...and see if the ammount of urine is the same ammount w/o drinking anything other then urine...some organic fruit and vegitables would be included in my diet.
