Burning flashes in my stomach - Ways on coping with reflux rebound?

Hi! I'm 17, diagnosed with oesophagitis grade A and I'm already on day 2 off of Pantoprazole (40 mg/day for 2 months). However, I immediately experienced this burning sensation in my stomach and a little acid coming up my throat, then burping. I had endoscopy last June and found out there was a hole-like thing above my stomach lining (told it wasn't ulcer) and I was negative on the H. Pylori bacteria so I suspect I'm having a reflux rebound? 

Any tips on coping up with the symptoms? Preferably the natural way. My gastro advised I take a capsule of Pantoprazole or Gaviscon IF NEEDED. Although I don't want to start another session on any PPIs as I'm afraid I'll become too dependent on it (or I'm actually now huhu). Thanks in advance!

Have you had any side effects from PPIs those 2 months while taking them? Did you take them daily? Which brand were you taking?

Hi! Not really? Just classic reflux symptoms 'cause I burped a lot and sometimes had a bit of acid coming out during those two months but nothing else. Yes, I took them around 8 am, everyday before eating. The brand was Protonix Pantoprazole (40mg)
