richard,
What are your most problematic symptoms?
Maybe if you list them we can suggest what might help best for you.

For me I get mostly muscle pain & tightness across the upper back and then it will spread to neck, upper chest & shoulders if I don't do my stretches & self care. But it took me a couple years, lots of reading and some really good PT people to get me to that point, where I can maintain myself.
I do still go to chiropractor once a month also. That comes in handy when I have managed to set something off and need a bit extra treatment.
