If I were you, this is what I'd do before trying Remicade:
1. Start a rectal med, maybe Rowasa (a mesalamine enema) and use it every day for at least a month. Then, if you get into remission, try to taper. I'm using it twice a week now.
2. Take a probiotic
3. Consider using prednisone SHORT TERM to get into remission.
4. Stay away from the foods that bother you! :)
Really, it doesn't sound like you're in *that* severe of a flare yet, and I think you have other options to try. The biggest reason I suggest this is it sounds like Asacol worked so well for years.
Status: Remission since late May 2009!
Symptoms began in November 2008, ~4 weeks after giving birth to my son.
Diagnosed with pancolitis on 1/30/09
Currently taking Asacol (400mg 4 pills 3x daily), Rowasa twice weekly, Natural Factors Ultimate probiotic 12/12 Formula, and Zoloft (25 mg).
