I quit Tuesday, June 24th, 1997. Felt a little lump in the roof of my mouth, got scared, it turned out to be nothing, but I decided that the pleasure I got from smoking was not worth the fear of what I might have done to myself.
My brother, who smoked two packs of Camels a day for 35 years, said to himself, "If Andrew can do it, I sure can do it" and quit too, in August of '97. Neither of us has smoked since.
You are doing yourself, your wife, and your child a great favor.
For me, the key was that it was *my choice* to smoke or not to smoke. There is something in this about free will - your assertion that you will choose what you will do, and no physical addiction will tell you what to do, or make you do something you choose not to do.
Off my soapbox now. Best of luck to you. Strength when you need it, and if you need to vent or just discuss, feel free to e-mail.
Regards,
Andrew
