I have recently been diagnosed with Crohns and have just started prednisolone. I have six weeks to go tapering down from 40mg. I have been experiencing some mild insomnia but have managed to get some sleep. However the last few nights I have had severe restless legs and can not stay still?! I do not smoke or drink, and do not drink a lot of caffeine. Is this a normal side effect, if so it it likely to continue for the next six weeks?? I am also on the following medication: ciprofloxacin, mesalazine, metronidazole, ranitidine and thiamine. Any help you could offer would be great!
