well the good news about cigarettes is that when you quit cold turkey you won't be sick for too long! unlike a hard drug like Heroin quitting smoking won't make you vomit or give you the chills! most of it is in your head although your body will want the nicotine it will just stop needing it as much as every day passes, but try to reward yourself every day even if its a little something to say i went another day without smoking!
good luck!
