Napping really needs to be tailored to each patient. Make sure you do what works for you. When looking for ideas see whether the patient making the suggestion has similar symptoms to you.
First, ME patients are often different from each other. What works for some other ME patient might not work for me.
Second, even when looking at a single patient, the symptoms of ME often change after being sick for many years. Sleeping/napping ideas that helped me in the early 1990s do not work for me now.
When I first got sick back in 1990 I slept A LOT. At my worst in 1991 I was sleeping maybe 12-14(?) hours each night. And I was also dozing quite a bit during the day on most days. I had hypersomnia.
Now, I sleep much less during the night. I sleep between 6-8 hours (it varies) with lots of awakenings. (Too many details to list here but my sleep problems appear to be related to my autonomic dysfunction - orthostatic intolerance)
But I don't nap during the day. I actually never even feel sleepy during the day.
I do force myself to rest A LOT during the day. Without resting I'd spiral down and get worse and worse.
Pacing is crucial for me. It's NOT a treatment, it's just a way for me to keep my symptoms from getting even worse.
But I never nap.
(That almost sounds funny - "never nap." Anyone remember the "never nudes" from Arrested Development?)
This got a lot more long-winded than I meant....
but I hope it was helpful!
