As the body acclimates to the two-step protocols of the Ultimate Detox System, you may experience fatigue, sluggishness, and light flu-like symptoms. These effects typically last from 3 to 14 days. If the effects do persist longer than 14 days it is best to lower the detox level. If symptoms worsen it is best to consult your physician.
