Have you considered drinking alkaline water for reflux? I haven't had this problem yet but my DH is a regular with acidity and reflux problems and we have this alkaline water pitcher at home thar we use...he finds it to relieve his acidity symptoms without having to take any antacids.
I take zantac 75 also&it has turned into my best friend. Like she said above it only gets worse.
My midwife suggested I switch from Tums to the extra strength maalox chews for antacid and gas...much more helpful and the gas relief is wonderful!
Coupd try drinking milk before bed that help me.xx
You can talk to your doc. I am taking 75 mg of zantac twice a day.....and be warned.....it only gets worse as you get further along....
