I am 25+ pg with DC2 and have the most horrible heatburn, I had it with DD and Gaviscon worked a treat after meals, now I can't even drink a glass of water without ending up with crippling heartburn. I could drink gaviscon, eat gaviscon dual tablets all day and still sit almost in tears after eating. I asked the MW and she said 'it's just part of pregnancy' and it will go away after I give birth. I can't live like this for the next 14.5 weeks. I avoid food to avoid the pain right now and I can't not eat until the baby arrives.
