Will the vomiting never end?

Ok- we are going on a week now of either vomiting or diarrhea and frankly I've grown tired of it. It has only been Aiden and Ophelia thankfully, but come on! Is there no end in sight? They are both so calm and good about it, that I hate to complain. They are just so pitiful though. I am just tired of vomit-end of story.
