Good for you man, I can not really give you any tips since I have never smoked anything (seriously, never) However I can tell you what's happening when you cough. I worked in a medical animation where I had to show the effects of smoking in the lungs... what you cough up is the mucus formed after the alveoli in your lungs get destroyed; so you are basically coughing your lungs out, slowly. I hope that you visualize this and use it as encouragement. Quitting will add apprx. 10 yrs to your life.
There was an exhibition of real human bodies without the skin in Atlanta a while back called "Bodies" one display towards the end is a pair of healthy and diseased lungs showing clearly what it looks like... next to it was a transparent trash can which was overflowing with cigarette packs from visitors after they took a look at the display.
Ah I found the link:
BODIES another motivator would be that you would be saving a ton of money and with prices of oil and food sky rocketing it will be handy the extra cash.
Good luck!
