As far as the way you smell goes, I think it depends on what you eat. The more sugar or caffeine I consume the worse I effect other people. Like I said earlier, I'm not a doctor, and my kidneys are fine as well. But I have smelled an ammonia like smell coming off of myself and I've seen how others react to it, coughing and itching. I don't know the how's or why's, but this is one symptom of our condition. Of that, I am sure.
