Ginger.......suck a piece of glace ginger until the taste is almost gone, or grate some root ginger and pour boiling water over it......add a teaspoon of honey and drink while it is still warm (sieve the bits out first) You can use the gratings more than once, but they do get weaker the more times you use them.
Small meals...sit up to eat and for at least a couple of hours after food.......the baby is stopping the stomach from emptying efficiently and the hormones of pregnancy can relax the ring of muscle that closes the gullet...making it easy for acid contents to leak back into the gullet(reflux is the technical term) and that is what causes the problem.
Not much longer to go now though.
I hope my suggestions work for you.
