Floss, I tire very easily and many times I will have days where I need to sleep, sleep and more sleep.
One of the problems that 'we' seem to be guilty of that adds to the tiredness is that on a good day, we push and push to get as much done as we possibly can and then we pay for it for about another week in pain and or in bed.
I am just as guilty as the next person! Yesterday I had to get out of the house. My youngest DD and I went to do errands and were gone about 5 hours. I came home and sat downstairs before going up to my room and within those few minutes, I became so still I could barely move. When i stood up, I was all bent over and could have cried at the pain in my feet and legs.
I noticed that the list of medications you take could be adding to the tiredness and the many hours of sleep. I do not know how often you take the oxycodone or the phenegran, but if I were to take those, I would have to kiss the day or night goodbye. My oldest DD takes skelaxin for back injuries from wrecks she has been in and when she takes those, some days she will be okay and others, she will sleep the day away.
Have you had a sleep study done? I have noticed a pattern among many of the people with fibro. Many of us seem to need CPAPS for apnea.
