sorry to hear about your father filthie... It must be a hard time for you . You are doing the right thing giving up though.
Until March last year i was a pack and a half a day man... but I decided to give up because of the financial cost, the bother about having to go outside for a cigarette when socialising, and to be frank, the final recognition that I was an addict, which irritates the hell out of me.
For me, the first 5 days or so was the hardest... thats how long it seemed to take to break the actual chemical addiction. I elected to go cold turkey, because I dont really rate the idea of tailing off using patches or whatever.. but I know that they do work for a lot of people.
It took a further 6-8 months to be free of the urge to smoke, to find something to do with my hands when watching TV etc, but the craving was gone.
I found it very helpful to drink water or eat when i got the cravings, but the side effect of this was putting on a fair bit of weight which I am trying to lose now.
If I did it again, I would get lots of apples and oranges and have one each time i felt the urge to smoke. Now, i find the thought of smoking abhorrent, and the smell of smoking on those who have been out for a ciggie break is actually unpleasant.
Anyway good luck in your efforts... just bear in mind the goal at the end.. addiction free, healthier and much better off financially :)
