I'm sorry to hear you're FM is acting up so badly. If I had any other suggestions than what you're already doing, trust me I'd certainly pass it on. Especially if it were free or inexpensive. I find using a hair dryer on high heat helps me warm up quickly. Particularly my feet and feels good on my hands and wrists if they're especially sore. I'm not sure why that helps. Maybe just psychological because of the noise and distracting heat. Get lots of rest for the fatigue. Pushing yourself won't help. My experience anyway.
