I'm usually pretty good when I'm not on Prednisone, but when I'm on Prednisone, it is SO much harder! When I start to wean and I have a bad day, I realize and give myself a few days to readjust before I call the doc back to consider not weaning so fast.
I find it hardest when I'm at the bowling alley. Not much I can eat there and I'm there a LOT because I'm an active bowler AND volunteer quite a bit.
Try not to beat yourself up. In the beginning, i was fast and hard about NOT slipping up... on anything. As it progressed, I learned that once I was in remission, a french fry here and there was okay or now I can drink soda, but couldn't before. I notice that with each flare, my ability to eat certain things changes yet again.
GL and just take it day by day..... it IS hard!
