I was wondering if anyone has this same problem? When I'm having lots of fibro pain or migraines I sleep around 18 hours a day. Yesterday I slept 15 hours. Is this the way my body is just shutting down because of the extra pain? With the fibro I do have days where I can't sleep and then I just roam around at night or go thru my magazines. It really helps me to read before I go to sleep. But I just don't understand why I can sleep 18 hours.
