Hi Jan Jacobsen. We have a lot of wonderful videos and programs on sleeping. You may want to visit this page to see what we offer: https://grokker.com/mind/better-sleep

These are some of my favorite programs on sleep:
Progressive Relaxation: https://grokker.com/mind/mindfulness/program/relax-mindfulness-meditation-practice/5501d7a2e7ad06765109d8ff
Sleep Smarter: https://grokker.com/mind/better-sleep/program/sleep-smarter/5b15cd49a77f4f48ea879421
Deep Sleep Release: https://grokker.com/mind/better-sleep/program/deep-sleep-release/5ab116646d0f12755ed29645

I've also attached some videos on stretches you can do before going to bed. Perhaps these will help you.

I hope you find something to help you. Having insomnia is really challenging.
