From what you're saying, this sounds like it could be me. What's the diff. be/ fibro. and CFS? I think CFS is a symptom of Fibro...but I could be totaly off! I get the foggy feeling and I also get tired a lot and achey joints sometimes, etc. How should I find out if this is sometihng I have? (I think I'll wait until this med leaves my system tho!)
