You may get a lot of very different answers to this. Not because people want to dissent, but because Fibro is such an individual disorder - there is no one (or even five) thing(s) that will work for everyone. If there were such a thing, everyone would be using it and there's be no problem.
I personally do not think that using a lot of medication is the way to go. I have done that and don't feel it did me any good in the long run. There is definitely a need for some pain relief when it is over-the-top, but that may not be in the form of a pill.
My personal advice is to keep getting as much activity into your day as you can. Get up, do something. Stay close to home so you can go back and rest if you need to. Do stuff around the house. Rest in periods if you need to, but MOVE your body in some way throughout the day.
Eat the healthiest diet you can for your own body. For some people this is plant-based, for others it is meat daily. Do what makes your body feel good, and if you don't know then experiment.
Stay as positive as you can. I get very heavy depression, so know at times it is almost impossible. But even when I am mentally on the bottom, it is not hard for me to remember that compared to the majority of the rest of the people on Earth I am wealthy and live in luxury, and am very fortunate. I focus on that when I can't be positive about anything else. But when I can, I try hard to think positively as much of the time as I can. Example: OK, so I had to cancel that plan and don't feel good today. Maybe tomorrow or next week will be better.
Don't live on Hope that Some Day Things Will Be Better. Live today! There is usually something that you can find to bring you joy right now.
Some say acupuncture helps; I have not tried it. Try what appeals to you, but avoid getting discouraged if one or another thing doesn't help. Just consider it research. You will eventually hit on the combination of things that works for you.
But the moving of the body and the healthy eating are not optional. Those are required for decent health no matter what, so not doing those things can only make any condition a person has worse.
Hope this helps.
