.. And most the important thing, quit smoking!
Quitting is often hard, man is better off not starting addictions like smoking, alcohol in first place and caffeine too if you may. I say so, because I tried to get rid of this generally accepted addiction of tea/coffee in early mornings and it was hard — I couldn't do it, my brain was too much restless, could not function without giving it's cup.
I told my mom, you should not have created this habit of giving tea in the mornings when I was little kid, because old habits die hard.
