GERD: You likely had some severe reflux regurgitation of acid on top of chronic acid reflux... Should start some anti-reflux meds and be seen by an ENT if it persists.

Throat still sore?: If your throat is still sore 4 weeks later, you need to see a doctor as soon as possible. I am not sure why drinking caused it, although with very heavy drinking, people fall asleep and get acid reflux, which gets down into their trachea because alcohol intoxication suppresses cough reflex.
