I‘ve been struggling with Fibromyalgia since 2007 which is very similar only maybe a little more pain and less fatigue sometimes. At one point I could barely get off the couch without help. I’ve made a lot of environmental and diet changes slowly over the years that have helped but it’s still a struggle.

I recently started an herbal recovery program by Dr. Rawls that seems promising and has had a lot of positive results. It runs for 2 months but could be used up to a year. Since it’s focused on all auto-immune disorders it may be helpful for your friend. I’ll let you know how it’s working after 2 months.
