My Chrons and Meds possibly changing

I'm new here,have had Chrons for over 40 years, have always been on sulfasalazine, librax, librium, lomotil, Zantac. Last few years Remicade 1000mg every 7 weeks. Started on humeria on September of last year and stopped Remicade, it seems to be working much better than the remicaid. Also put me on Laila 2tabs every day. Now in March he wants to decrease the lialda and sulfasalazine. What do you think? Also have diabetes,insulin etc. would appreciate opinions. Thank you.

I haven't heard of either of those, either. But @brelaxed is right on the efficacy (or lack thereof) of mesalamines.
