I was a smoker- and on the day I quit- I signed up to this forum. The best advice I can give is don't look at is as quitting smoking- because that is a horrible thing, because if you are anything like I was- cigarettes are your friend. They calm you down, they are a treat when you finish something, a pick me up when you feel down, a social thing to do with a friend, and by focusing on simply quitting, well thats where i went wrong. But I really went for it this time by being committed to my health. I knew i needed to drop a few excess kilos, and really made the whole quitting thing part of my new life. I focused my energy on excercise and healthy eating. I must say the hardest times for me were on the weekends- when I'm out having a drink with friends.
I wish you luck- IT'S NOT EASY! Don't listen to anyone who says it is! But it IS 100 times more rewarding than being a smoker. And it is achievable. You can do it!
Life's a garden, dig it!!!
