"Especially since you obviously have a healthy system since you report drinking a cup at a time w no negative response."
This was also interesting to me. I read in many places that for up to a week U.T may cause effects ranging from nausea to full on illness and vomiting etc. Many personal accounts spoke of this also. I had no real problem with the taste of my urine (I have been drinking cough syrup for years to get high, after all...) so I went right into drinking most of what I produced with absolutely no ill effects. I'm glad to hear that this is a sign of a healthy system.
