I'm 26, will soon be 27 and I've been smoking since roughly 18 years of age. I am really, REALLY wanting to quit by or before 30 especially with my health in the shape it is. My question or questions I should say IS: Anyone here successfully quite smoking and if so what product did you use? OTC(over the counter) or prescription? Side-effects and how long did they last if any? Most importantly how long did it take you and how long had you been smoking prior? Thanks in advance for any helpful information guys.
