I think your answer is dependent on too many other things not mentioned to get you a correct answer.
Although I can tell you that strong itching all over the body using UT therapy in a basically healthy individual is not normal.
If more water and healthy dosing of probiotics and probiotic enemas do not take care of the situation consider your diet and other cleansing programs. Maybe cut back if your urine is not sweet.
A coffee enema might cure the situation fast if you are seriously having itching problems. Lie on the right side and let the liver sit with it for a few minutes. Legs over head if possibly to get all the way up the tract. You could also try a urine enema.
I personally found I could continue UT. Just have to contend to other matters too.
