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 🤣
Have you tried Pepcid?? It’s the only thing that helped me during pregnancy
