Hard to tell for me, too, whether or not it's MS. I was diagnosed with colitis as a young teenager--misdiagnosed, I think, because I was much later diagnosed with IBS and that is probably what I've had all along.

The only thing that's worked "well" for me (in other words, without gruesome over-cure) is being careful to eat fruit, veggies, cereal with fiber, etc. and drink lots of water. And keep magazines in the bathroom.
