Yes, Steve, I do. Sometimes I ache all over and am tired. Other times, I am bright and alert and peppy. Problem is, the peppy only lasts for a very short time, then I crash. Sometimes I sleep and sleep and wake up full of brain fog. I am tired all day and need a nap in the middle. I say I am in my tired cycle. Other times I sleep only till 3:00 a.m. and feel really bouncy (I don't get up though), however, by suppertime, I am dragging. When I am peppy, it is never for very long, but it is extreme!!! I feel like bouncing all over the place. Might last for an hour or so. Then I crash, my mood swings from extremely happy to severely grumpy. And the aches - they go on for weeks, and then disappear for a time, only to reappeaar somewhere else down the road.
