Anyone managed to fix this, naturally / holistically

For around just over two years now, I have been getting bouts of insomnia. I can remember the first night it happened, before that I could just lay down whenever and I would be asleep within an hour maximum, worst case scenario. But that fateful night, I was laying there and the hours just kept passing and I had work the next day. Fast forward over the next few months, there was a particular week where for 3 - 4 days I could not sleep at all, or only had around 1 g 3 hours and had to take two sick days at work as a result.

Since then I have had periods where the sleeping went back to normal, getting 6.5 - 8 hrs per night, but then it comes back. I have tried acupuncture and other alternative things here and there sith some good results. However, it is still persisting, I have also had some luck with meditation, making sure I am hydrated,.not eating too late etc. textbook sleep hygiene does not work so well for me, some of the best sleeps I have had in recent times, has been when watching a movie for example, causing a strong drowsiness. However this is all mixed results and I am still struggling, making going to work very challenging. So it is all in all, an intermittent yet persistant issue. When I struggle it's like something in my brain/body just switch off. Especially if I have something to do early the next day, it's not even that I'm necessarily anxious, could even be positively excited. But I have gone to my physically demanding hobbies with 2 - 3 sleep as a result of laying awake until the early hours of the morning, it happens almost everytinme lately. But I don't want to let the insomnia win, so will often just get through the day regardless. Hoping to hear from like minded people, I don't want to rely on any tablets, or get into any debate about it.
