I can sympathise with you, I have had HB since week 12 and it seems to be getting worse. I was tolerating it up untill week 22 when I started mylanta and i'm now on zantac (which is not reccommended in first tri) I found tomatoes was one of my biggest triggers, also spicy foods, fizzy drinks, my in laws tea, (i'm fine with my own tea). I hope it passes for you. I found milk helped.
