Has anyone here tried amitriptyline and did it help? I've seen some significant improvement (hallelujah) with this which affects your acetylcholine which can speed up signals to the body and something I've wondered about with FND. I got ill too just after I gave up a bad coffee addiction and coffee can keep your acetylcholine down if high which is what may happen in FND. Starting coffee again unfortunately did not reverse this effect. Coffee isn't great for the hormones anyway!
