Fellow MFPers with IBS?

Hey guys - Are there any groups of IBS sufferers on here? You can't search for groups anymore and my perusal of the top ones didn't find any.
I feel my IBS - which unfortunately is a big part of my life and my diet - has massively changed throughout my weight loss and I'd love to have people to talk to who have undergone similar things (and perhaps not offend some of the more squeamish). Thanks in advance!
