Welcome to the forum! It sounds like you're in the right place. Sorry to hear you woke up with such an unpleasant and painful episode. It sounds like you're treating yourself with OTC medications...have you seen a doctor about your problem?
It may be acid, rather than bile. If you're on PPI's, then bile is likely the culprit, but if you're just taking OTC meds like Zantac or Pepsid, and you have reflux bad enough to wake you up, it's most like acid rather than bile.
Do you have the head of your bed elevated? If not, try getting bed risers (or put boards or bricks under the legs at the head of the bed.) (Hopefully you don't have a waterbed, because that's very bad for reflux.)
Maalox or Gavascon, or something like that is your best bet until you get to a doctor to discuss the problem. You won't want to let it go, because your esophagus can be damaged badly by reflux over time. You stated that you don't have a history of reflux, but I suspect you have had something called, "Silent GERD"--reflux without being aware of it.
Again, glad you stopped by. I'm sure others will check in and provide some of their own experiences and advice.
