Like Chickpea I noticed a big difference when I had to come off the CellCept for surgery earlier this year. My neurological symptoms came back with a vengeance. I was glad to be able to get back on it. Right now I'm on Plaquenil, methotrexate, and CellCept, as well as numerous other meds for symptoms and other AI conditions.
I've had a flare recently of the neurological issues (balance, PN, vision issues, etc.), and the docs wanted me back on steroids, which I have really been avoiding with my bones being so weak. So instead they have upped the dose of methotrexate and will up the CellCept if the methotrexate increase does not help, and then finally put me back on steroids if necessary. None of those meds are fun, but the damage to the nervous system from the inflammation is worse. At least I can still crawl around in the dirt and weed my garden!
