Acid reflux due to antibiotics. Throat?

Hello, I was taking amoxicillin from past few days due to some injury. Last night I took it and I ate food in the morning without consuming pantocid. Turns out that food has got stuck in my throat due to acidity. I have tried taking pantocid but could not even gulp that, threw it up. I have tried taking Digene and did gargle. My throat feels choked due to acidity. If this condition persists, I won't be able to eat anything or take other medicines. I am getting continuous burps. When I burp, I feel food pipe has opened a little bit but after that it gets compressed again. Could someone please advise what should I do or consume in order to clear my the acid in my throat? how long will it take to clear my throat? Please help. Thanks!
