Have Had Sleep Disorder For 15 Years. At First Was

have had sleep disorder for 15 years. At first was only getting 2-3 hours of sleep at night. Now usually I get 4 -5 hour. Vitamin D has helped recently and some rugs for sleep problems have worked at times, but with bad side-effects. Now I get headaches behind the eyes and back of the neck. Sometimes see blue spots in my sight, which are getting bigger and more often.
