My son started having some flu symptoms Saturday. He had sweats and chills yesterday, but those have pretty much subsided. He currently has diarrhea which has been going on since yesterday morning. He is taking Imodium, drinking Gatorade, Sprite and water. He hasn t eaten a lot, a couple pieces of wheat toast. I know there is a ton of flu-like illnesses going around so just wondered if there is a better over-the-counter medication for his diarrhea. He has been sleeping for about 2 days which is very good!
