I was a smoker for 10/11 years. Started at 15 years old and now at 26 I am 9 days smoke free. I'm using Chantix and it is really helping me. When i smoked my last cigarette, I was so scared because I had tried to quit many times before but it hasn't been that bad. I still think about smoking a couple times a day but I find that I can quickly get rid of the thought to smoke. I have recently started coughing up brownish/blackish mucus.......(gross I know). But that shows me what was inside me! I am looking forward to working out again and being able to breathe!
