Hi Roald...
I can help you with CBD if you want to try that route. Works like a miracle for some, does nothing for others. Valerian root, ashwagandha and a few more are similar, but best to pick one at a time so you know for sure whether or not it works.
For me, it worked well for a bit, then pooped out despite taking the odd break, but for my father, it has been a life saver. Again, mixed opinions on the forum over the months and years.
Biggest thing is that you need to find a reputable source. Make sure you buy from an established vendor who publishes their test certificates. Make sure those certificates have the name of the company that tested... look up that company profile and make sure they are legit. A lot of legwork, but worth it to know you are getting the right stuff otherwise you could be spending $$$ and just getting olive oil.
If you were in the UK I would know where to send you, so as an example look at this company;

These are the sort of documents you are looking for.
Feel free to ask any questions.
