Anyone else have mornings where you wake up feeling rested and wired then within 30 min. you feel as though you could fall asleep standing up? This often happens when I fall asleep much later than usual. After 4-5 hrs. of sleep I wake up as though I have had the best nights sleep.(usually having to pee is what wakes me up)I get up feeling rested and not to painful then within 30 min. I feel as though I havent slept at all to the point of being light headed. Then the pain begins and it is a struggle to get through the day. If its a weekend I crawl back in bed and thats pretty much where I spend the rest of the day. On a work day like today I just count the min. til I get back home.
