absolutely stay away form oatmeal...i can't eat it either...it's way too much fiber...and i have ibs also.....what works for some....does not work for other...when it comes to ibs....i have found that out the hard way. I have had ibs for well over 20 yrs and believe me i think i have tried just about every thing to eat...and really for me, it doesn't matter what food it is...it all depends on the day i have....some foods will do me differently at different times...it's trial and error really. Good luck.......have you tried Digestive Advantage? Buy it at Walmart...CVS....works great.
