Hi, My Husband Is 54 And In Generally Good Health.

Hi, my husband is 54 and in generally good health. This morning, he woke up feeling well, had a light breakfast of an oat muffin and a small amount of blueberries, raspberries and blackberries. An hour later, he had diarrhea a few times. He bought Ammodium; then about 3 hours later he vomited 3 times in a row, more diarrhea, etc throughout the day. He has only had Ginger Ale for the remainder of the day. What else can he do? We're hoping it's a 24 hour bug.
