A lot of people use Rowasa for maintenance. I've been seeing my GI more frequently than evern 6 weeks (I was just diagnosed in January), but I was really, really, really sick. My guess is that the caffeine makes your UC symptoms worse, but probably didn't trigger it.
Symptoms began in November 2008, ~4 weeks after giving birth to my son.
Eased for ~3 weeks in December, possibly b/c of probiotic use?
Returned in January 2009 (with a vengeance), diagnosed with pancolitis on January 30.
Currently taking Asacol (400mg 4 pills 3x daily), Rowasa nightly,
40mg 30mg 20mg 15mg 10mg of Prednisone (quick taper), Culturelle probiotic, and Zoloft (25 mg).
