You need to re-train your routine Bonnybanko, we are creatures that like habit. Personally I go up at 9, no tv or mobile phone or kindle. I have the radio on low, a talking programme, I put my electric underblanket on a medium setting. Prop myself up with two pillows and I knit, just plain easy and mindless knitting. In about 45 minutes my head starts nodding and it is time for me to sleep. I don`t re-awaken myself with teeth brushing etc
Getting up, also a routine, similar time every day
I wake during the night, eat a small oatcake and turn my radio on very low and on a timer. Next time is always waking-up time
