Hi, Charizzy. Welcome! You've gotten some great info already from Snowbunny and ak angel.
One thing that makes Fibro so frustrating is that it's often so hard to find the combination of meds, exercise, diet, etc. etc. that works best for us, because we are each dealing with a different chemical makeup, other conditions, and so on...there just isn't one right way to go, for the most part.
I do think, though, that everyone would agree it's important not to sit or lie around too much if you can possibly help it. Some people can exercise way more than others. I'm one who has to be very careful, but then I recently had spine surgery and I'm no spring chicken.
We really love to help eachother around here, so I hope you'll keep posting. We understand what it's like to have this maddening illness!
Debbie
