I realize it works quickly. But I keep seeing people talk about the HORRIBLE side effects (which I've also experienced). After going through that 8 years ago, I swore I'd never take pred again. When I flared up severely in January, my GI of course suggested pred. I reminded him that I refuse to take that and told him I'd deal with the Crohn's symptoms before dealing with the pred side effects. It took longer to get my flare under control, but it was better than what I went through with pred. Anyone else feel that way?
