Is it acid reflux???

Tonight I woke up because my throat was burning like crazy! It was like everytime I swallowed something was bubbling up in my throat and making it burn. I couldn't take it anymore and got online to try to figure out what it was... I think its acid reflux. What does one do to help acid reflux. And this has never happened before, is it related to the fact that I at a huge supper tonight, and it was all pretty much junk food (potato chips, cookies, goldfish, cheese dip, burgers, more potato chips). I've had a ridiculously annoying cough for a long time (its been here since about april or so...I had bronchitis and the cough stopped producing mucus, but it never went away). Does this symbol something that is going to occur often, or is it just a one time thing do you think? If it will occur often, are there any certain foods I should avoid, or eat that will make it better?
