i second the hypno tapes, as well as trying digestive enzymes, ones with plant and animal enzymes in them, that was one supplement i didn't see on your list, they can make a huge difference. The GNC multi enzymes seem to do well for a lot of people here. Also you can try Traditional chinese medicine. i had good results with herbs mixed by my DTCM, they were specific to me and they helped tremendously with gas, bloating and the reflux i used to deal with. Good luck.
