Hi Emma
I suffer from esophagitis anyway so heartburn is quite a frequent visitor. Normally I would be on medication but as am now pregnant don't want to take anything, plus I keep getting allergic reactions to meds. Anyways, the rennie chewable softmint are quite nice and defo more effective than the chalky type rennie.
They sell them in packs of 3 tubes in boots with all the other rennie's.
They're just like a proper chewable softmint so more like a sweet than heartburn stuff.
They're obviously not as strong as proper medication but they are safe to eat during prenancy and you can eat a whole tube in a day and they tend to do the trick, or if not they defo take the edge off.
I know how you feel with the discomfort, it can get really painful at times and I hate when it stops me sleeping too.
