My opinion of the matter is that ANY chronic illness can lead to some pretty bad consequences over time. For instance, that sleep problem you have can easily lead to Fibromyalgia, Myofascial Pain Syndrome, and a host of other problems as normal brain chemistry is affected by lack of stage IV sleep. When I first became ill it was pretty minor, so I refused pain meds & such....until that stuff started happening to me. Good luck with everything!
