Avoid driving or hazardous activity until you know how lithium will affect you. Your reactions could be impaired.
Avoid becoming overheated or dehydrated during exercise, in hot weather, or by not drinking enough fluids. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
Do not change the amount of salt you consume in your diet. Changing your salt intake could change the amount of lithium in your blood.
