I remember the first time I woke up in the middle of the night with acid reflux. I was literally choking and a little sick and was really startled. I had heard of this before but it was a real freaky experience. I'm not a regular sufferer and it turns out mine was caused by the type of strange diet I was on at the time. I was eating chicken wings late at night and not really giving them time to digest properly and it was causing all sorts of drama. Anyhow I modified my diet and thankfully it never happened again.
