I have been taking Omeprazole as and when required for 15 years. I can weeks without any. All of sudden 2 weeks ago I started getting acid indigestion that perservered and would not be shifted by the medication. It could persist for 2 or dYS AND THEN suddenly be OK for a day or two, I am also burping more. MY Gp thought it may be a sliding hiatus hernia and told ne to take 2 tabs a day for a week then 1 for a month. I am at the end of the week and still no better. It is strange because whe I eat my measl it is OK for about 15 mins then starts up again. So I see some sites suggest not eating various foods as they are acidic. This cant be right as your stomach acid is around pH 1.5 and much more acidic then any foods you will eat or drink? Any comments would be welcome please.
