I am 77 and have fibromyalgia diagnosed 14 years ago. I am always feeling exhausted, and am unable to stand for very long or walk very far without a mobility device. I need to nap during the day. Now I have been diagnosed with sleep apnea during REM, as well as anemia, both of which could explain why I am so very tired. I will be getting a CPAP machine very soon, and can hardly wait to experience a good night s sleep!! Do you think the improved sleep might improve my anemia as well, so that I will not need to take iron supplements?
