Hello all, for the last 3 nights as soon as I try to sleep my stomach starts gurgling and churning and I get terrible heartburn. This goes on all night and is only relieved in the morning when I go to the toilet. I don’t have a mad dash to the loo it just churns, gasses and refluxes all night. I have suffered with my tummy on and off over the years, had colonoscopy all clear. I have recently started Sertraline but these are quite severe symptoms? Any advice would be appreciated x
