Hi, New to this message board. I have been diagnosed with FM and have been given a rx for Flexorel, I have been taking it as prescribed everynight 3 hrs before bed. the next day I wake up feeling unbelievably hung over. Does anyone know any other medications that won't give this bad of a sleep effect. Do other's feel this effect when taking flexorel? It's bad enough I am always exhausted but now I am literally falling asleep at my desk. thanks.
