I had incredibly bad heartburn with DS, from around week 15 onwards milk did nothing for it and instead I was necking Gaviscon straight from the bottle. I avoided all foods that seemed to set it off (garlic mainly) and had so many pillows in bed that I was practically sleeping upright. The old wives tale was true for me - full head of hair and even hairy shoulders!
I'm 20+5 with this one and it's even worse! The Gaviscon is back out and it's doing virtually nothing. Anyone got any tips that I can try?
