What oztin said would certainly help!! Although I personally get great benefits from raw honey. But if you are not ready, or don't ever want to give up your less healthy habits, doing urine therapy whilst having these won't hurt. In fact it should help clean you out. You may come accross some healing crisis symptoms as your body struggles with the toxins you are giving it at the same time as the cleansing power of UT.
I don't know what your reasons are for thinking of doing UT, but if they are health related then as oztin suggested, there are many things you could do for yourself before you did urine therapy. If your drawn to UT though, then go for it, unless you are on any drugs, medicinal or otherwise.
