i have been smoking everyday for like past 4-5 yrs... wake and bake for how long i dont even remember... now i moved to a different city, havent smoked for 2months+ ,I noticed I get more irritable, impatient and aggresive, restlessness and insomnia....i wished i i'd never smoked that much in the past..............smoking once in a while is okay, jsut have urself under control. ... otherwise it gets harder to live without it.
