I quit smoking for 2 years already. For me, the most difficult thing is when smoking become your habit, especially you will have one right after you had your meal, it is very UNCOMFORTABLE when we stop doing it. Seriously, sometimes I just feel like many tiny ants are running underneath my skin, begging for the nicotine. Luckily I found the way to reduce the uncomfortable feeling, I keep drinking cold water when I want to smoke, it makes me feel better, you can try this too...
