I'd ask for a prescription from your doctor. Sounds like over the counter meds are not strong enough for you. There are pregnancy safe options available.
I drank soda water, the fizz really helped. I kept a can next to the bed for overnight wake ups. And propping upright
Ginger might help, my partner says tonic water but ew lol It’s awful luv sending hugs
I was on Omeprazole my whole pregnancy. Baby came out full of hair 🤣
20mg Pepcid (famotidine) twice a day and peppermint candy helped me. I got that prescribed by my GI as it was the best pregnancy safe option and I had extreme pain with acid like you! It takes a couple of weeks for it to fully help
Have you tried Pepcid?? It’s the only thing that helped me during pregnancy
