When I had my bleeding peptic ulcer my hemoglobin was at 7. My heart was pounding like a freight train. I had no nausea or gas. They cauterized my small intestine. I only drink decaf green tea, unsweetened almond milk, 9.5 ph water and low acid half caffeine coffee in the morning with unsweetened almond milk as a creamer. I refuse to give up coffee. Almond milk is alkaline. Give up booze, soda and all citrus juice. No vinegar products at all. A good book is the acid watcher diet. Good luck and I hope you find relief.
