So very much.....I will look up those levels....and I do have zanaflex....I took half a tab last night and no cramps this a.m. Maybe things are evening out...but there has been a bruise/knot type pain from the first one that happened over a month ago....several sx leaning more and more to MS but no one sure yet...........all systems are malfunctioning at once!!!! Hopefully I will get some testing this week that will show something somewhere.....second time at Johns Hopkins I pray they figure out one tiny itty bitty thing....my arms are real fatigued, my whole self more so,MRI changes, neuro sending me for PN or some demylenting disease.......I spelt that wrong I know. I'm glad to hear i'm not alone with this and for the kind advice...will update....

oh shelley by the way does the cortef make you shake and tremble with exertion of ANY kind and sweat like crazy? Besides the mood swings. I had to reduce from 30 mg to 20 and still can't stand it.
