A lot of the problem is how it takes over your life. So you are constantly worrying about should I have had that glass of wine, I forgot to meditate now I won't sleep, blah blah blah.
After years of insomnia, fingers crossed the better sleep continues as it's only been a week so far, I realised that rather than bedtime being sleep time, my body /brain thought 7pm was 'rest' time. So, having woken/started the day at 3am, by 7pm I was glad to slump in a chair and watch tv, peruse the internet (not for long as I knew that the bright light can affect your sleep), and to relax. I'd always been an early bird so getting up early wasn't a problem , staying awake in the evening was.
Then I realised that I worry and mull things over at 3am but never at 7/8/9/10pm. So I think my brain/body thinks 7/8pm is 'rest' time, I doze happily in front of the tv, therefore 7 hours later (a good average night's rest), 2-3am is wake up time. I'm wide awake, worrying (often about how shit it is having insomnia).
I now keep on the go into the evening, doing online puzzles, using a SAD light early in the evening to read by, hoovering, housework. Just staying alert and away from the 'I'm exhausted must sit down' mindset. Then relax at 9.30, bed at 10 (or when I'm tired, whenever that is) and I find I am able to get back to sleep after waking between 2 and 3.
I had a DH who can sleep anywhere and for as long as he chooses so there was a lot of lying awake and silent for me, while he slept, which was stressful. I'm retired now so can suit myself, I move to another room and listen to audiobooks, the radio, read. So if I am awake it's as pleasant as it can be.
