Quitting nicotine - enjoy the pain
My goodness it's painful. Focus on this daily pain and how it gets incrementally less painful each day. I say focus on the pain because it feels far better than the pain and destruction your lungs have suffered in your chimney days, I bet they are literally bleeding right now. Enjoy the paint, that dry thirst for that soothing nicotine, enjoy it each day as it slowly evaporates and your lungs start functioning normally again.
