Hi Dougal, I was on Omeprazole for years (I'm 41yrs), suffer from IBS & reflux, was taken off Omeprazole by Immunology as they thaught it might be causing my symptoms (peri menopause) put onto Ranitadine instead. I used to take peppermint capsules also, stopped these since started taking probiotics & generaly my reflux is much better controlled. Although I am trying an experiment today & tomorrow (not taking Turmeric supplement on fast days) I have a suspicion it makes me more refluxy whereas other non fast days I'm fine & have been mainly since starting HRT & improving my diet & losing weight, all contributory factors (poor diet & being over weight!) I hope you find something that helps or a combination.
