Struggling with acid reflux

Hi Mama's! I'm nearly 10 weeks pregnant and my acid reflux has started up again over the past 2 weeks. I was treated for esophagitis in the fall after suffering from reflux for a while. I'm now off prescription meds (was on Dexilant for about 4 months) and decided to look for natural remedies after learning about the damage PPI's can cause. So far, I've been getting by okay with apple cider vinegar, pickles, papaya enzymes and even HCL supplements, since most of us with reflux are suffering due to LOW acid, not high acid! The past couple of days have been more of a struggle even with a bland diet. Sore throat, chest discomfort, nausea. Tums do nothing and I realllly don't want to go back on a prescription. Are there any natural remedies that work for any of you? I'm willing to try ANYthing! I've been so careful. I sleep with the head of my bed elevated. I've stopped consuming caffeine, citrus, chocolate, spices and grease. I'm getting 30-60 mins of physical activity every day. I'm just so frustrated!!! :(
