The standard advice I've heard is that if it smells bad, dump it out.
If your body is detoxing, then, your body uses your bowels as the primary system for toxin elimination, and then uses secondary systems such as your circulatory system (which urine is a part of), skin (through sweating) and lungs to get rid of toxins. So, if your urine contains toxic waste products, re-ingesting large portions of it is probably not a good idea. But, you can still dilute it and use it homeopathically.
You can use uropathy to purify your body and make it pristine again. Once your body is clean enough, and you'll know when that is, then you can drink it all, 100% all the time, night and day, and it will never smell or taste bad.
I have been drinking mine, 100% of it, for almost 6 months now. But I started doing it 100% only after about 14 months of uropathy, starting with morning only and worked my way up to more and more of it each day.
It's an easier, more comfortable ride to go slow with it, if you have the luxury of time and you're not seriously ill.
