Holy heartburn/acid reflux!

Ta
31 weeks here and my heartburn and and acid reflux is back with a vengeance this past week! It happens even when I don't eat any of my heartburn triggers and even when I don't lie down after eating for several hours. Sometimes it just happens because I eat anything and sometimes because I haven't eaten in a while. It used to be just heartburn but now it's more of an acid reflux. Sometimes while I'm sleeping I'll wake up feeling like I might puke from the burning reflux sensation. It's making it very tough for me to want to eat anything. Anyone else going through this? Have you found anything that works? I feel like I'm back in my first trimester but worse with the reflux this time. I really don't want to have to take OTC heartburn/acid reflux meds for the next two months. Any natural remedies that you have found that work or is this just another pregnancy symptom we have to just learn to deal with until baby comes?
