Good morning Milly!
Although I do not suffer from Fibro...what you describe fit's many of us to a "T" ...It is a long tiresome journey, and even harder if one is not medicated correctly. Keep plugging away at it, and avoid those activities that start a flare. If you feel that you are still under medicated, then let your Dr know this. Even then it may take a long time to get it right, or at least to a point that you have some sort of quility of life.
At the moment, I'm under medicated, but my Dr is conservative, and creeping up on the dosage slowly, and it is of course, it's 30 days in-between appointments, and certianlly no fun. Are you on any extended release medications? If not, then you might take a look at one of those.
Hang in there...I know it's not easy...and I'm sorry you are suffering.
