Yup, the steroid munchies!
I tend to have them injected but was put on pred tablets this morning, 8 a day so bracing myself, although I feel so crap I'm more bothered about feeling better.
I have inbetween steroids periods where I try to get good routines in place and don't eat so much so I can't eat too much when the steroid munchies hit and find out of sight (or easy reach) can help too. One of my downfalls is cereal bars I have at work as better than chocolate - if I eat one and there are others left...too tempting! I find fruit good, if I stick something like a punnet of grapes in front of me I'll just go through them - got told off by dietician though as apparently shouldn't have loads of fruit in one go.
Not much helps the weight gain though and puffy face.
