Yesterday morning, my husband diarrhea. Then this morning my husband asked me if I heard him being sick in the middle of the night (vomiting and diarrhea). Thankfully I didn't! Then he just called me from work to tell me he was sick again. He says he feels OK, though, and he doesn't think it's anything contagious. He sometimes gets diarrhea when he takes too much Advil. Do you think it could be a stomach virus?
