I would consider consulting a naturopath who can determine the cause of your UTI woes. It may lie with the health of your liver, kidneys, colon, etc.
You can also try acupuncture which could significantly reduce your problems by itself.
For me, my UTI woes (burning while urination) went away by following the protocol and getting over die-off. During the die-off period the toxins caused too much stress on my body and it caused this burn.
