Feeling like crap

I have had the absolute worst heart burn these last 24 hours. Constant vomiting because of it, and then pure exhaustion and pain from the vomiting. Does anyone have any suggestions to feel better? Meds aren’t helping the heartburn. I’m avoiding eating/drinking anything that could trigger it. I’m 37+2 weeks and just so ready to be done. I could barely sleep last night due to the heart burn and I’m very nervous about going into labor with barely any sleep like I did with my daughter. I currently feel flu-like because of it 🥴
