Holy heartburn at 36+4

So

Have had awful heartburn for the past week or so. Waking up in the middle of the night awful. Been trying to manage it with the usual no spicy, small meals, no lying down 1 hour after eating, etc. I’ve been needing to max out on Pepcid every 24 hours. I’m exhausted. I am at risk for preeclampsia, not sure it’s related. Have my doctors appt tomorrow so I’ll bring it up.

Any natural remedies? Tried milk, ginger, and TUMS make me nauseous.🥺
