1)Drink plenty of fluids before and after infusions.
2)Bring candy as suggested...I bring cinnamon candy. It really masks the metallic taste.
3)Eat a low-sodium diet during and the day after your infusions are finished. No more than 2000mg of sodium. This will help reduce weight gain.
4)You might get a headache and have some difficulty sleeping...but I always notice a diminishment of symptoms within a day or so.
