I know that CFS can trigger hypothyroidism, and so can adrenal issues. I'm trying to figure out if post exertorial malaise, and non-restorative sleep can manifest itself for hypothyroidism like it does for CFS. Let's use a hypothetical scale of 1-10. 1 is slow walking. 10 is intense weight lifting. Monday: 6-7 (moderate cardio) Fatigue factor: 1-2 Tuesday: 9 (weight lifting heavy) Fatigue factor: 0-1 Wednesday: 7: (weight lifting light) Fatigue factor: 5-6 Something's starting to happen, pushed through it. Thursday: 2 (nothing) Fatigue Factor: 7-8 (random bouts during the day) backed off, however the fatigue begins Friday: 2 (nothing) Fatigue Factor: 7-8 (random bouts during the day) Saturday 2 (nothing) Fatigue 7-8 (random bouts during the day) The other part of hypothyroidism or adrenal fatigue that I have is the non-restorative sleep. I can get 9-10 hours, but it never feels like real sleep, it dosen't feel deep and restorative when I wake up. Sometimes a quick nap in the afternoon or evening can feel more restorative than 10 hours of sleep. Since I was sub-clinical hypothyroid (TSH 4.5) for a period of time (before the crash), and still had restorative sleep, I'm trying to determine if more severe hypothyroid symptoms / adrenal fatigue can cause these two issues, as they do in CFS.
