Me too been on Pred. for a couple months now. Started out at 8 pills - 40 MG per day and can eat like a horse. Easily gained 10 pounds and all the side effects, acne, sleeplessness, huge appetite (never full), grumpy etc.
Wish I could exercise to mitigate the weight gain but I am also on Methotrexate and my knees are bothering me too. Can't run or walk hard or else my knees ache.
As I am tapering down the Pred. my Crohn's is flaring up. Down to 5 pills 30 MG and having blood and loose stools again. Was fairly well under control when I was on full dose Pred.
Seeing GI specialist again in 3 weeks and we'll see what the next steps are.
