Have been suffering with awful indigestion and acid reflux. Have been trying to see if I can work out what triggers it but at the moment it seems more or less everything does! Gaviscon was helping a bit but didn't work that well. My GP has prescribed ranitidine. I feel less nauseous but acid reflux and general discomfort still going strong. Has anyone taken this? Did it work straight away or does it need a while to kick in? Many thanks.
