I start sneezing when I drink like coca cola, or eat something that is loaded with preservatives . What is in those chips?
Also, whenever I get stomach cramps, I also get back pain. They go hand in hand, I believe, because of the nerves in the area are related.
Have you ever tried a little baking soda in water for trapped wind? Perhaps it would reduce your symptoms after you liver flush. Since you got stones out the last flush, it would probably be a good idea to continue. The stones can't be doing you any good.
