Does taking medication like Immodium help if you are suffering from the flu symptom of diarrhea? Providing you aren't vomiting too much to take the Immodium. The kind I take dissolves without having to wash it down with water.
BTW my father who was born in 1909 lost a little sister to Influenza when he was a boy. That would have been the time of 1917. They had on picture of her & my dad taken before she had become ill & that's about the only rememberance of her they had.
