I'm right there with you. Over the weekend I was up over 50 hours, then I slept like 19 hours. Tried to have a normal day yesterday, but was in the dumps and on the verge of tears most of the day. Slept 9 hours last night and woke in a murderous rage this morning. I've always been a rapid cycler, the older I get, the harder it is on my body and mind. Hang in there, you are most definitely not alone
