hi there, I am in exactly same boat. been on prednisone for 2 months now, going on 3. gained 7kg the first month, was on 40mg a day, now down to 20mg a day. i started eating healthy last month and lost the 7kg gain last 30 days. been stuck on 91.4 for 4 days now. it is the medication i promise you. i am on prednisone, dapsone, colchicine, after bloodwork it came back that i have overactive hyperthyroidism plus anemia and that all together causes urticaria breakouts. im going to see the specialist in feb. i am trying my best to maintain and even lose a few kg's but its hard work with little results. somedays i dont even want to weigh myself because i know i did not even lose 100g. but also its a lot of water weight, keep telling myself little by little day by day. then there is the moods! irritibility, anger, tiredness, tummy trouble, depression, anxiety, numbness. oh i can go on, but it wont help. so please be patient with yourself like i am also trying to be. stay (slightly) positive and celevrate the small victories.
