OMG Heartburn!!! 🔥🔥🔥

I know you rarely escape pregnancy without it but man this heartburn/indigestion is getting INTENSE! I've tried tums and Zantac (on the recommendation of my doc) and both worked for a few weeks but now not so much. I've tried a million natural remedies: milk, sleeping propped up, not eating 2-3 hours before bed, almonds, no liquid w/meals, apple cider vinegar & cutting out high fat/fried foods. Nothing is helping!! I'm 30 weeks on Monday and don't know if I can take another 9-10 weeks of this! Anyone in the same boat w/suggestions that have worked for them???
