Congratulations on managing the fibromyalgia so well! That's quite an accomplishment. And now Essentials Tremors. Wow.

I think the Movement Disorders Forum will put you in touch with people familiar with that:
http://neurotalk.psychcentral.com/forum65.html

Introduce yourself there, ask questions (e.g., any connection with fibromyalgia?), look around.

If you don't find answers there--or if you like a 2-pronged approach--try the Fibromyalgia Forum:
http://neurotalk.psychcentral.com/forum12.html

Same deal: intro/ask/explore.

Keep coming back. Keep asking questions. Let us know how you're doing--with your diagnosis, treatment plan, especially how you're feeling about it all.

This is a big place with info, social hangouts, all sorts of stuff I'm still discovering. Hope you find it as welcoming, informing, & comforting as I do.
