With Chronic Fatigue Syndrome, there is no such thing as “feeling rested or refreshed” after a sleep of up to 12 hours. Worse, I have no stamina, so some days, getting out of bed is as good as it gets.
Other days, I can walk to Walmart, but each thing I do must be followed by a few days to a week of down-time.
Naps don’t come easy, even so.
I usually head for bed after 1500, but I will read until 1800 or 1900. If I stay awake any longer than that, I’m so wired I will have insomnia for three nights or more. It’s the nature of the beast.
Does anyone ever recover to any degree? I worked with two people w/CFS, and they became shadows of their former selves. I lost track of them, so I never found out if they felt better as time went on.
