When I first started I'd eaten asparagus the day before. The pee was quite bitter and very strong smelling. I drank it anyway!
Since i've varied the diet, sometimes the pee tastes just like coconut water.
Funny thing is when I drink alot of coconut water my pee seems rather strong and salty.(I think my body is using all the good stuff in the coconut water and not recycling.)
Anyway it all remains somewhat of a mystery how it all works.
Suffice to say it does indeed work!
