I'm no expert on ulcers, but I know a lot about heartburn
and GERD, and I'm almost positive you have at
least those. I'm not a big advocate of medications, especially long term, but the Zantac doen't seem to be working. You do need to see a doctor, but at the very least, pay attention to your diet. Excess weight around your mid section can put pressure on your stomach and force the contents back up your throat. Sitting for hours isn't great for digestion either.
