Milk and honey, then make sure you prop up when you lay down.
I had warmed milk before bed hoping it'd help and nothing. I was propped up in a recliner chair for a good 2 hrs before I layed down for bed too. I just feel like crying. I don't like the feeling of heartburn at all.
Drinking pickle juice helped me, if you can stomach it down..
Your doctor can prescribe you a special medicine to help of nothing else works. I know you said you wanted home remedies, but it's better than being in pain bc it affects baby too. I wish I could help more.
Pepperment gum or peppermint candy
