Actually, it's funny, I have IBS-A, so I sympathize with both teams!
My C is what takes me out for days... UGH! I get so tired and depressed. Sometimes I can't even get out of bed for long (except to go stare longingly at the toilet!).
But as an unexpected "treat," yes, D wins hands down!
Hope I made someone laugh, at least! I don't feel too sorry for myself (what a waste of time!), so only recount stories if I think someone will get a giggle...
