My niece was married Saturday. We were busy at the church from 6:00 to 9:30 on Friday night. Then again from 12:00 to 5:30 on Saturday. I stood through the wedding, then through most of the reception serving cake and punch, then helped with cleanup. I got up on Sunday and felt like I had lead weights on my arms and legs. Sort of like you feel when your blood sugar goes too low. But no matter what I did, I couldn't "boost" it back up. Eating and drinking didn't help, so I don't think it was blood sugar. I just couldn't do anything but lay around all day Sunday. I guess that's my cue that I can't do that kind of non-stop stuff anymore. Is this the "classic fatigue" that I'm describing? I don't usually have too much trouble with that aspect of fibromyalgia, and certainly not to this level.
