I know you are serious, but I have to chuckle when I think of how you are going to try to get your aunt to drink someone else's urine. I drank my own urine while I was doing the mushroom, amanita muscaria (not recommended), and its taste is very different than its odor--but several years later without the assistance of anything, I tried to drink it, but just couldn't. I couldn't do it. However, when one does drink urine, I've heard it should only be drunk in the morning, and only when the urine is clear. 40 years ago and old man told me of a case of a woman with scarlet fever, who drank her urine because they wouldn't let her drink any liquids, and she was healed. I guess it has to be a very serious illness--which cancer is. But I wouldn't drink my own if I were doing chemotherapy and those drugs--and I really don't know if someone else's would do any good. It may be an auto thing. On the other hand, if I had cancer, I guess I'd be saying, fill it up (if its clear) for breakfast.
