I smoked a little over 15 or so cigarettes a day for 7 years, found out I was pregnant and quit cold turkey. I could never quit before getting pregnant, he's been my only motivation. There are tons of support groups out there and just so you know, it gets easier but it's still hard for me after almost 4 months, I even dream about smoking lol. I wish you the best of luck and congrats on trying to quit, that's better than nothing!
And I haven't walked into a single gas station since I quit lol, that helps too. I'll leave my ID in the car (which you don't need unless buying beer or using a check, really). That's helped a bit.
