any meds to increase the motility of the colon?

been suffering from either ibs or ibd for 5 months this bout.  got a few opinions from different GI docs, and they still don't seem to agree on the diagnosis.  nevertheless, my main symptom seem to be lack of colon  motility.  i still have bowel movements, but they are not like my usual ones.  my pain significantly subsides when i can get some gas out.  my psych that's treating me for the IBS portion suggested i talk to GI bout increasing motility meds.  but when i ask them they give me a blank look.  i just started Amitiza for 3 days.  but from reading the method of action, it doesn't increase motility.  any ideas anyone?

thanks

i think some supplements might be more helpful than meds. the amino-acid L-glutamine is the most abundant amino acid in the body and it is part of the fuel behind the lower GI tract. it is also brain fuel and is the precursor to GABA a amino acid that can help with relaxation and anxiety and pain. the B-Complex is a important component. Garden of Life and New Chapter both make a B-Complex supplement that has natural Pro-Biotics in it that might help you. Garden of Life also has a miracle product for me and i am on high dose opiates with one of the main side effects being constipation, it is called Super Seed beyond fiber powder that is great in smoothies or juice. A good aged garlic extract can help or apple pectin tablets or capsules with meals. Chia seeds is a great new super food that can cure gut problems. best of luck to you.
