Today is four months without a cigarette ! I just wanted to say thanks to everyone here tha t is willing to share advice ,knowledge,and guidance to new people that are getting in to vaping to help quit smoking . I'm a volunteer fireman and four months ago a 22 minute air tank would last me about 12- 13 minutes and went to afire last night and my tank lasted me 20.5 minutes . I was the only smoker in the department and my boys were so proud of me they bought another eleaf tc40 to keep in the truck so I don't have to grab mine as I run out. So thank you everyone that helped me have a good night
