Yeah I know pain is just part of it, then comes the foggy thinking, etc.
Lyrica can help pain but it can make one foggy / sleepy.
At one time I was told that not getting into a deep sleep will negatively affect Fibro. Years ago my PCP placed me on Zyprexa, anti-depressent, to help me get into that deep sleep. It worked but I felt like a zombie.
I do hope that you find something that works for you so that you may get your life back.
Best Wishes,
