heartburn is killing me ☹️🔥😩

EC
I've had heartburn pretty much the whole pregnancy, now about 29 weeks. The last week or so my heartburn had been WAY worse - I am still taking my tums and Zantac and it's not helping. I can deal during the day but it's so uncomfortable and keeping me awake at night. I've been trying to prop myself up with pillows when I lay down and I drink ice water for a little relief. I used to use apple cider vinegar before I was pregnant but now it just seems to make me nauseous. People say drink milk but it doesn't help and I am lactose intolerant. Just complaining... I feel bad whining Tommy husband all the time ☹️
