Anxiety and stress may be reflux triggers, but that's not my bailywick. Hopefully you can find more by searching the website. There's also a whole forum for that here.
So you had the same common problem with Reglan that I had. The facial twitches. Fortunately you recognized it before it became permanent.
It may not be the actual alcohol that causes your reflux but the other stuff in it. Beer and wine are notorious for sulfites. Mixed drinks often contain corn syrup in the mixers, which also contain sulfite.
Caffeine has its own problems, notably acid. You could try drinking less and going with the less acid varities. I don't have a problem with coffee itself, but the junk mixed with it - sugar not labeled cane sugar, corn syrup containing creamers are sulfite-containing triggers for me. I also have a lactose intolerance and don't do well with milk protein either, but soy milk seems to be ok.
Yes, do log what you eat. Try it for at least a couple of weeks, preferably a month. You might just find that avoiding your triggers keeps you from needing meds or surgery. At least it's a free test.
