Margreet that's where I was. I couldn't train my brain off. I tried all of the tricks. Getting up, sitting in a chair and reading until I was really tired, meditation (that always worked for me before), keeping my eyes open in the dark until they closed on their on. melatonin. Stopping the melatonin. Finally I decided no naps during the day no matter how tired I was, drinking plain sleepy time time tea from the super market (a counselor gave me this tip) before I retired, and trying to go to bed at the same general time at night. By 9:00 I was wiped and it finally helped. Naturally since my sleep rhythm was so off I woke early (too early) but I began to regain a bit, a 1/2 hour, then an hour, sometimes only 15 min. But now I'm almost back to normal. Last night I slept 7 hours. Believe me I feel your pain. I'm still waking early between 4:30 and 5:00, but I feel better overall with this added sleep time. Now I can watch a TV show until 10:00 or even 11:00 sometimes. Often I can't. But it was so important to find a way back.We require sleep.
