Acid reflux

Brittany
I am 12w6d and this is my 3rd pregnancy, this pregnancy has been by far the worst! I have HG...that seems to be fading away now my acid reflux has came and it's HORRIBLE. The doc said do zantac-well that's not working anymore and I have no idea what to do. I am miserable as all hell....any suggestions or advice, I'll take any. Thanks!
