Does any one have any miracle remedies for the mother of all heartburn? I'm 29 weeks and so far have sailed through with a really healthy pregnancy. I'm now plagued by severe almost constant heartburn. I mentioned this to the midwife on Friday who did me a prescription to collect on Tuesday for something similar to Gaviscon, however in the meantime, I'm eating Rennies like they're going out of fashion and consumed half a pack of Gaviscon in 5 hours yesterday!
