Cammy, you may just be on the wrong 5-ASA product. Be sure to talk to your doctor about
the possibility of switching to Colazal, as it has been much more helpful to many of us. Also consider following the suggestion to take a good probiotic. You should be able to get them at any pharmacy (chemist's?) or you can order them over the internet. If you do a search here, you'll find many discussions of probiotics.
For now, try looking at the amount of insoluble fiber you're eating - things like oats, other rough cereals, raw fruits and veggies, etc. Sometimes cutting those will help the cramping.
And hang in there. I think most of us have been where you are, I know I have. There are better things ahead, you just have to keep plodding forward until you get to them.
