Heartburn is killing me

Someone tell me how to get rid of this heartburn because tums arent cutting it anymore and neither is magnesium or milk or apples 😭 and dont try to tell me the obvious. Eat small meals, eat slow, don't lay down for an hour after you eat. It's too late. I have fire hot heart burn all day everyday no matter what I do. I just want it to ease up for 5 minutes 😭
