I smoked for about 15 years - 2 packs Marlboro's every day. Then on Sunday morning, 10 April 1983 (I still remember the day), I woke up with a ton of chest/lung pain. I rolled over, grabbed the pack laying beside me on the nightstand, wadded them up & tossed them in the trash can. I never looked back, never had a craving, never touched another - flat out COLD TURKEY. Now it's been almost 30 years & I'm still smoke-free...of course, I then got fat! LOL
