I'd be curious to follow along and read more. My experience is that everyone's body is quite different and what causes chronic issues with everyone can be quite different. That's not to say his observations and solutions won't be useful to others, but it's another good anecdote to understand and things worth trying for others having similar issues.
I myself for example have had headache and migraine issues for more than 25 years. I understand deeply an incredible amount about what causes my migraines, how they feel, how I help with it, and so on. I understand migraines more than anyone else I ever know in my life because I observe, pay attention, study, and try different things so much. I understand it more than most doctors I talk to. But I also know that everyone's migraines are a little different and not everyone gets triggered by the same things (though there's a lot of overlaps) and my solutions may not help for everyone. I'd totally write something like this for migraines if I had the time (I don't :( ).
