Some days I can't get out of bed because I am too sleepy. I have slept 3 days without getting up except to go to the bathroom. I feel this is a physical problem but nothing seem to point to this, this has been going on for years. sometimes in the evening I will feel good enough to do household chores. I do have fibromylgia, pernicious anemia, and had breast ca 2 years ago which has gone well.
