I get it everyday, its horrible isn't it.
Most days, the part of acid heartburn that I HATE.. is the burping up of the burning bile.... Normally when I'm at my desk.. and have to swallow it back down
During the day time, I eat melon to help with my brekkie, Lunch isn't tooo bad, then when I get home, I drink water, with my dinner, then some milk and some gavisocon (I find that gaviscon helps "prevent" it rather than actually helping when I have it)
Then when I go to bed, a few hours after I have eaten, I have another small glass of milk
(BTW - I hate milk, but it does help.. occasionally)...
Failing that... I have a rennie!! I know you're not meant to take tooo many of them, but the odd one of 2 won't hurt... surely.
The NHS helpline said they are ok to take.. but not a lot, and don't exceed the stated doseage.
And here's some of these.. as acid heartburn is pants....
