If enzymes don't help you should be taking Betaine HCL. If your Diarrhea is constant you should NOT be consuming Xylitol, Erithritol, etc.

You should carefully read the ingredients on your multivitamin as well. Also you should consider food allergies . You are taking way too much stuff on a daily basis to figure out what might be causing harm.
