Ugh - sorry to hear about your pain! I had a bad experience too.
As per my Doc - I am on 40mg of Nexium 2x/day, Zantac 300mg, and Maalox as needed (helps with those foamie gas bubbles).
He gave me Carafete, every 6 hours which helped, but gave me bad diarrhea, so I stopped and the Maalox helps now when I need quick relief.
Had an endoscopy which turned out normal. Had an esophageal manometry (tests esophagus function) and still waiting for those results.
Eating food helped me - if I just drink shakes, Water, etc. it seems to be worse.
Good luck to you - hope you find some relief SOON!!
