you can do it! i was a chain smoker and realized that i couldn't be the best i could be if i didn't quit. it makes such a huge difference in your stamina! i had a college roommate that was a very serious in-shape athlete that quit smoking and remarked on how surprised she was that she felt the difference (since she assumed she was in such great shape despite smoking). my lungs thanked me and so will yours!

any updates on how things are working out for you?
