I suffer from heartburn quite a lot after having my gallbladder removed. Rennies don't seem to do much, and I hate chewing chalky tablets. I did find some tablets called Ranitidine in home bargains which were good, but they seem to have stopped stocking them now. Can anyone recommend anything else that works? Is the liquid gaviscon any good? Last Christmas I only had one glass of fizz with lunch and couldn't drink any more, or eat much either.
