Has anyone else noticed an enormous improvement in mental clarity with Cymbalta? I've only been taking it a few weeks, but am so happy about this. Unfortunately I also seem to have a lot more insomnia with this med. I hope this clears up, and the mental clarity remains. The pain relief is pretty amazing as well. My main complaint is CFS, not the fibro. I guess I didn't realize how bad the pain still was without the drug.
