It's day 6 since I've quit smoking cigarettes and honestly I can say that I've never felt better. My pee is clearer and doesn't stank as much. I can actually catch full breaths of air, heck I felt so good yesterday morning that I went for a run, and proceeded to cough my lungs out afterwards but then felt even better after that! Also, all I gotta do is think about the 30-50 dollars I didn't spend on smokes this week. Could easily contribute to a nice cut of nugs .
