Like others the things that give me acid reflux is tomatoes, tea, coffee, pastry, fizzy drinks, mashed potato, sprouts, crusty buns or bread, alcohol, mint, too much chocolate, strawberries but love them and buy 2 punnets every weekend while the british ones are in season (yes I'm a glutton for punishment) and stress!.
Maalox Oral Suspension is very good. I have been having Morrisons brand Fruit flavoured antacid tablets. 48 tablets in a box. I sometimes only need to have a half a tablet in the day and one before bed if needed. they don't cost much, in between £3-£4 I think. I prefer to chew them and swill down with water. They can be sucked but I tend to get a thirst if I do that.
