Get back on the probiotics. I second the Renew Life Ultra Flora Critical Care and I would suggest as well you try the Reuteri.
How many Asacol are you on at this point? You did taper them...could be part in your symptoms.
Where are you at this point with the enemas?
What you're taking with the psyllium seems fine....take it with your meals maybe that would be better than alone.
