hi dan boy, i was never prescribed ritalin for fatigue. i try to just rest as much as i can on really high pain days and try not to overdue it on days where my rsd is not as painful but still hurts. i also try to eat healthy and am now trying to lose all the weight i gained since i've been diagnosed with rsd. combo of meds and inactivity contributed to weight gain. i think that losing weight will help give me a little more energy back. i also try to walk a little bit when i can so i get some exercise in. mild water aerobics helped increase my energy a little but i had to stop after a few months because of the cold water and all the surgeries i went through after getting rsd. maybe you could try mild water aerobics if you dr okays it and if there is a place near you that offers it. i hope that you feel better and less tired soon. take care.
