Have you tried keeping a food diary? Also, has your doctor mentioned getting you onto a PPI medication? Now that you've taken antibiotics twice, you will need to replenish the good bacteria in your body by taking probiotics. Thins like unpasteurized sauerkraut and yogurt or kefir are great for this. You don't have to shell out for the expensive stuff. I had h pylori twice, and the antibiotics really destroyed me. I am now taking Prevacid in very high doses. Before you try to eliminate this h pylori again read about if you really need to. Also, I think that urea test was done way too soon after the first time!
Good luck to you! And hang in there, I've been dealing with this bad stomach thing for years! Watch what you eat and drink, and get a second opinion!
