I am a 18 year old female and have been smoking for a long while now. In the past week after smoking I have gotten a cold sweat, stomach pain, thrown up, and blacked out twice after smoking a cigarette. After about an hour of sweating and throwing up about every 5 minutes it quits. I get extremely hot as well. It s weird how it randomly started doing this. What are reasons why, besides smoking is bad for me and I need to quit, this is happening?
