Problem: Going to bed later and later because I'm not tired/can't sleep. Currently getting to sleep around 2am. But very tired around 8-9pm. If I do sleep at 8-9pm I will only nap and then be awake for even longer before proper bed time. Why is my circadian rhythm shifting? This has been happening for 1-2 years now and I hate it. I've had ME for 6 years. Severely for the last 3. I sleep well for 3-4 hours then have to get up to pee. And then sleep in 1.5-2hr shifts from there due to nocturia of unknown cause. So it often takes me 9 hours in bed to get 7 hours actual sleep. I have checked my blood sugar and it's good. I make sure I'm not hungry when I go to bed. The room is the right temperature. I read before bed. My room is really dark. I go outdoors in the day to get decent day light. I'm not a fan of drugs and would prefer to get to the root cause if anyone has any ideas?! I do have severe adrenal fatigue that no amount of supplements has helped!
