Remedies for heartburn??

Ladies help! I’m 22 weeks and 4 days and I’ve had heartburn pretty much the whole pregnancy but my goodness it has gotten so much worse. I can barley get through a meal because of it and I will get it before I even eat!😩 sometimes even when I drink water lmao is there any home remedies you can suggest? I talked to my doc a while ago he said tums and some other medicine that I can’t remember but I can’t take time because it makes me even more sick. 🤢

Any suggestions help! Thank you♥️
