I'd take it a step at a time. Sounds like you might end up with "too many cooks in the kitchen". I only see a board certified Internist and a board certified Rheumatologist.
I'm not a huge fan of taking a drug for this and a drug for that. I try to find things that are a more natural approach to this illness. This means gentle exercises like walking and swimming, pacing myself when doing things, getting gentle massages, and keeping a positive attitude. That has helped me as much as some medication. There is a link in Fibro 101 about maintaining a positive attitude when you have chronic pain. It really is very good.
One thing that helped me the most with my sleep was when I was prescribed a muscle relaxer...Robaxin. Before that, I was up 3-5 times a night by pain. I couldn't get comfortable, etc. Once I started the muscle relaxer I was able to sleep. I now only get up once to use the bathroom. Because of that, I'm resting better and that helps fibromyalgia. I am feeling better than I have in years!
I hope some of these suggestions help your wife.
