Fantastic….way to go!! I quit cold turkey a number of years ago and the only advice I can give it to think of it one day at a time or, if necessary, one hour at a time. "I will not smoke for one hour".......and then renew the commitment at the end of that hour. And shake up your routine a bit when it comes to doing things that you associate with having a cigarette. For instance, I had a BIG connection between my first cup of coffee in the morning and a cigarette. That was one of my biggest temptation times. Unfortunately, I couldn't find a real solution to that one and just had to gut it through. I had the added incentive of being pregnant at the time. It turned out to be a good thing that I quit when I did because my next child had severe asthma and smoke was one of the triggers. Someone I know had to keep a pack hidden in the house as a psychological crutch. She felt better knowing that it was there and she did successfully quit cold-turkey. I don't have the best self-control and I could not have had a pack in the house. I had to know that I'd have to get in the car and go and buy a pack! Another friend kept putting aside the money that she would have spent on cigarettes and then she rewarded herself with a "congratulations" gift.
What a wonderful gift it would be to your friend's memory - to give up smoking in her name.
Keeping fingers crossed for you and sending support your way...
