I felt awful for a few months - achy and difficult to get out of bed. Turned out to be a vitamin D deficiency. At the bay area latitude, we barely get enough especially if you don't go outside enough. Worse if your skin pigmentation is darker. Thankfully this is something doctors screen as part of a normal blood workup. It isn't CFS -- but if anyone is having a similar experience, check with your doctor.
