I have struggled with the same thing. I agree on the digestive enzymes and probiotics. You could have candidiosis (bad yeast overgrowth in your system) which a candida cleanse would be extremely helpful. You could also have a food allergy that you don't even know about. A great system that takes care of both of the above situations is www.lifeforceplan.com - this plan has helped literally change my life on many different levels including my bloating issues. Good luck!!
