My husband became sick on Tuesday with vomiting weakness, and a headache. He s a cyclist and attempted to ride yesterday and became weak again with a queasy stomach. He s very tired and just wants to take naps. Not like him . It s now Friday and he continues to periodically have a queazy stomach and Is easily fatigued and wants to take naps. He also mention that he gets light headed from time to time. He s been drinking Gatorade, ginger ale mixed with smart water and eats small meals. He s 68 years old and has a heart condition. Any suggestions? We ve been in AZ since early Feb and are planning to return to MI next Sunday.
