I gained 50# in about 6 weeks when I was on 60mg of Pred. I was also very mellow and ate everything in sight. Huge moonface, I had to wear my husband's jeans and was also getting acne, though much milder than you described.
A friend of ours was on a much lower dose of Pred and he was a maniac! His description: He could be at home and be brutal, *know* he was being brutal and harsh with his family, making them cry and hurting feelings left and right.
And... he... just... didn't... care. Then five minutes later he'd be sitting in a corner and crying. Just bawling his eyes out.
He couldn't get a handle on it.
Everyone reacts differently.
I have the ability of single-minded determination and accurate project focu....Hey, look, a cat!
Crohn's and UC are pretty darn crappy, but if you can't laugh at yourself, you'll cry......I'd much rather laugh.
2001 Dx'd with UC. No remission. No improvement with Remicade. 5/2008 surgery, removal of 6" of left side colon. Dx changed to Crohn's. Remission for 8-9wks after surgery, symptoms returned after resuming 6MP. Changed maintenance med to Methotrexate (MTX) and had great results with IM injections. Nausea and symptoms returning with oral MTX. Switched back to IM injections and am slowly improving.
