When on sickleave earlier this year, @Blue_Bird I was advised to stop drinking coffee too late, have tea instead which I enjoyed, and do some gardening which was enjoyable being among flowers. But also I had some wooden Venetian blinds, so come afternoon I flipped the blinds upwards to deflect the light to make a comforting glow on the ceiling.

I was advised to reduce my time on computer because light from the screen can keep me awake. And in the evnings I'd change into pajamas and read a favourite book. All this helped me. Reading can not only relax, reducing anxiety, but make us feel sleepy. After a month of all these, I found going to sleep less anxiety making, and enjoyed a good night's sleep.

Some evenings I listen to rainfall on my phone or computer. rain.today is a good site as is mynoise.net which can have its sounds saved to a bookmark. The distant non-threateningh sound of thunder + gentle rain makes for a wonderful night's sleep.

I hope you find some of these tips useful.
