Not sure about the chest pains. Sounds like it could have been a mental thing? Miralax could make butt burn if it made poop too loose.

Surprised the Colace Reacted to you like that Crayon, I havent had that problem the one problem so far is that it makes me gassy Like crazy! And I just hate that feeling of having to use the bathroom all day that it can give you Im gonna cut it down to the just two at night with the Mirlax. Jackamaniac I have never heard of Mirlax being a cause of palpitations but if it did and the other one didnt just stay away from it. Delasama might be right though sometimes your mind can play tricks on you. I have had that happen before when takeing medications.
