Came down with a very unpleasant stomach flu. I used Rhus Tox, a homeopathic, for the aches which worked like a charm for up to a few hours at a time.
My wife fortunately bought me a probiotic juice. I slipped on this and fasted with several drops of vitamin D added with each cup I drank.
Along with a lot of sleep by the next day I felt all but over my symptoms and was able to return to work.
