Hi Joan
I also suffer from acid reflux as do both my parents - i have a more mild form so i only take a low dosage medication but my father takes a much stronger one so your husband might need to go back to the doctor - he needs to be on a proton pump inhibitor - my doctor would not prescribe it initially as she said she does not believe in them so i went back to the specialist.
Acid reflux is when the acid that exhists in the stomach - "splashes" up the oesophagus and burns. The proton pump inhibitors reduce the production of the acid so it wont "splash" up.
Certain foods make the condition much worse - even if the tablets work. I cannot drink orange juice or any other very acidic drinks. Real coffee is a trigger for many people. Hard cheese is a major trigger as well.
I hope this helps
