I have Been tobacco free for 21 days now thanks to the vapor cigarette. Last night I thought I was going to die. After laying down for 15 mins I started getting pains in my chest and lower stomic. I have had heartburn in the past so I took a whole bunch of tums. Still feeling the pain I layed on my stomic which helped the pain go away and feel asleep. Well when I woke up I still had pain in my chest area and can feel it when I breath. All day I have been in denial of it being from the ecigarette but It is. I have never felt like this before in my 13 years of smoking. If anyone has ever had this happen or has any input on it let me know please. I love vaping so much and need it to quit smoking but it's killing my lungs.
