Sporadic acute GERD tips

Every year or so I get acute GERD caused by something Im not sure what it is. Probably a mixture of food and stress.

But during this time, I literally have to sleep sitting down for like a week and a half. It’s awful. Spend all day sleepy and not like I can drink coffee to wake me up. Thankfully I work remotely and manage by taking few naps during the day.

Anyone has tips when you go through episodes like this?
