Patients can usually manage ordinary fevers due to colds or flu’s in the usual way (without changing the T3 dosage) if being maintained well on a certain level of the WT3 protocol. Remember that each change in the dose of T3 causes ripples the way a tap on the edge sends a ripple through an entire water bed, and these ripples can last for up to two weeks or more before settling down. These ripples may not be noticed in any side effects, and maybe not even in the body temperature patterns, but may be detected in terms of lost potential benefit.
