  9. its my 3rd day since i stoped smoking nicotine from e-cigarettes like juuls, stigs, cuvies and puff bars, and im experiencing anxiety feeling lightheaded and sad like i wanna cry for no reason, i also feel my chest tight, and having the fear of dying which gives me more anxiety yet, idk if im the only who is having these feelings but is anyone else do feel the way i feel???

  10. I swear it gets significantly easier after 2-3 weeks. Cravings are gone after 4-5 months. When you can stand around and watch your friends smoke while feeling no urge then you’ve done it. I quit not because of fear for lung cancer but because of the stuff they put in ciggs, that shit really fucks with your brain chemistry. Smoked for 8 years before I quit, over 10 failed attempts before succeeding. Every time you fail and most of you will, remind yourself that it is a process. Pick up that pack, smoke the shit out of it, feel disgusted with yourself, remind yourself how shitty smoking a cigarette feels then quit cold turkey. Repeat this till you succeed.

Keep up everyone. We can do it.

  21. I've been a smoker for 5 years and I really want to stop, but I feel like it's a part of me so I'm really anxious. I would like to gain weight but I think the cig are affecting my appetite and preventing me from gaining weight. So I would like to know if I would start to gain weight if I stop smoking?

  22. I didn’t know your body returns back to normal after you quit smoking this is amazing. One of my family members stopped smoking and never smoked again.

  23. Cmon..I am at 90hours now ..and believe me it is not over, it getting worst and worst. I am thinking about cigarets all the time. All I wish now is to smoke one, but i don't want to give up so i will fight

Some withdrawal symptoms are still present, like anxiety and upset stomach/flatulence (frequency significantly reduced). My breathing has greatly improved as well as my mental focus. Looking forward to sustain this.

  25. I lost my mom and aunt, and probably soon second aunt to this horrible habit. I now have 2 friends I love, going through this same destructive path, and I can't do anything to stop them…to help them. I'm watching them die 🙁

  34. There are many factors in quitting smoking including eg motivation and help from family.
    One resource I discovered that succeeds in merging these is the Quit Smoking Crusher (check it out on google) without a doubt the no.1 idea that I have ever heard of.
    look at the website QuitSmokingCrusher.com and incredible testimonials.
