Ive got it terrible and it is constant as well. I had it right through my last pregnancy and went through ridiculous amounts of gaviscon (which didn't seem to help) I have been taking rene tablets this time too but again it works for about a minute to five minutes then its back again. I have been told to try beetroot? Fresh obviously not pickled so will be picking some up next time i go shopping but any other suggeestions very very welcome.
