Is drinking pee healthy?

Well, I just wanted to confirm this here. I'm serious BTW. Is drinking pee healthy? Somebody told me drinking pee is healthier than drinking whatever she drank to produce it. Is this true? I need to know this because I usually engage in watersports play and I don't want to risk our health with this.

I've been a toilet slave for six years.  From my experience, it's best to spit most of the time, but if and when Mistress deems it healthy for me to consume, I'll greedily drink as much as she allows.

In short, you can safely consume urine in moderation, but if it's /all/ you drink, you can get very sick.
