Crabb, if your meds aren't working be sure you are no longer taking them (Aciphex or anything of the sort). These medications do not "cure" the acid problem, they merely attempt to reduce the feeling/burning symptoms. The only way to reduce reflux, as I have found, is to reduce stress in your life, and by controlling your diet (staying away from acid trigger foods) and body (working out). A healthy diet (no unneeded added sugars, fast foods, grease) and a weekly work out plan may rid your heartburn as it did for me.
Thankfully there are many more products out there that advertise themselves as being gluten free. If you don't have access to health food/specialty stores, most giant/chain stores are increasingly adding these products to their lines (ie. Safeway even carries fluten free frozen waffles).
