I agree with Sabrina that going without prescription meds is the best approach.
Our bodies got into this condition, I think, primarily because of stress. there are many, many different kinds of stress and one of them is what we put into our bodies that is not natural. More research is being done on this and it seems to be showing that people who have taken a lot of prescription medication in their lives, especially antibiotics, are more likely to end up with chronic conditions such as CFS, Epstein-Barr, and Fibromyalgia. people who take a lot of prescription meds to counter the condition of fibro usually end up getting worse and worse, having to take more and more meds, and so on.
Morphine, as you know, is highly addictive, and I suggest that you go off it. In the long run it will do you a lot more damage than good. You live in a state where medical cannabis is available, and I recommend you try that. Also, try going on a new program in which you take into account all of the things that have an impact on this condition, and which I have listed several times on this forum. (If you don't have the energy to look it up I will list them for you here).
The only medications I have tried that has success for me is --for back pain only -- two Advil and a muscle relaxant taken at the same time. doesn't do a thing for other kinds of pain, such as legs or shoulders or headaches, etc. The only thing that works pretty consistently for me for other pain is medical cannabis. It took a lot of experimentation to learn how and when to use it and the dosage but it has helped a lot. You just need to experiment and find what works for you.
You have to do your own experimentation, but start with the basics of taking proper care of yourself.
