I have recently, four days ago quit smoking, 30+ a day and gone from drinking approx 20 -25 cups of coffee a day, to drinking only four or five a day. Around about the same time, I also started amitrypteline, for chronic pain....for the last four days, and particularly at night have suffered indigestion, so much so that it keeps me awake at night, despite the fact that I take sleeping tablets, and am on numerous medications that make me drowsy....could any of the above be causing this indigestion?
