How many of you were really hard core smokers before vaping? I'm just wondering if it's me? I chain vape 36mg all day long and have since I started vaping 6 months ago. I was a 2 pack a day smoker for over 32 years. Heart racing? Mine races more going up some stairs, nothing when vaping. In the morning, I need to half drain a cart, drink 3 over sized cups of coffee and take a shower before I can even get blood past my collar bone! I've never had any of the things described since vaping, except for a couple of minor rashes, probably from getting used to the PG in my juice.
