I drank punch and ate 10 crackers about 12:00 am . Went to sleep about 1:00 am. I was awaken about 3:00 am with a burning in my throat and mouth with acid coming up. I proceeded to the bathroom I stated spitting out a mucous like acid in the sink. After this esisode I beltch and could still feel the acid in my throat. I chewed a couple of tums. Could this be acid reflux. This has happen before but not as severe.
