Steroids can make you hungry and eat more than you realize! Watch your weight, and if you begin to gain, keep written track of what and how much you eat. I think it might also involve not utilizing all the food like your body used to...anyway many ppl gain while on steroids, but IMO you don't have to.
I hope these preliminary measures bring you good relief

Please be sure to contact your local MS society. (Or call the National MS Society) or via net
www.nmss.org The understanding you'll receive, and the little things to do and not, are invaluable! TC!
