well some of us want to quit but we are a bit addicted in an emotional way!! and life without them can be more dangerous for us then life without them we are all made different!! and as far as saving time on ur life!! thats what they tell you !! they would do anything to make u quit!! who wants to live that long anyway!! all the studies, and fact are not in on this, like on anything else. they say heredity plays a big role in what diseases we will get. don't believe that one either!! as far as slipping, i don't know of anyone who has quit and not slipped up at least once!! or did it purposely because they just wanted a cig 1 day and took one!! however, it doesnt mean u have to keep smoking if you don't want to!! i have learned that if i smoke a cig or 2 one day and get back on track the next day it is so much easier!! As i said for me, int's not the physical it's the mental!! bottome line!!! and we are all different!!! i am pround of trying and for anyone else who tries, also for anyone who tries to quit any drug, i am very proud of you!! throw the alcohol in with it too!! a lot of people trade 1 drug for another, then i have to deal with more drunks on the road. so toss that too!!
