Here are a couple of good sites to start with. There is a ton of information out there about fibromyalgia.....some good stuff, some not so good stuff. I try to stick with the tried and true sites like the Mayo Clinic and nih.gov.

I understand it's a relief to be dx'ed but I am sorry that you have fibro. For me, everyday I'm hurting in a different place, I never know what to expect unless I've done something really physical (like shoveling snow), then I know I'll be hurting in specific places.
I was on neurontin a number of years ago for some MS like symptoms and pain (could have been a fibro flair???). It worked wonders for me especially for the horrible tenseness and pain in my legs.
Take good care!
