Excellent... thanks so much for taking the time to respond. We're going use everyone's tips and try the one week experiment. Ideally he'd rather find a diet that works for him and not have to be so dependent on Imodium and Citrucel, although we know that may not be the case. Even so, Imodium and Citrucel are far better alternatives than Humira, Remicade, Prednisone... etc.
He'll get through this... you're help and support is greatly appreciated!
