I too smoked from around 18 till about 23 years old,,, not something I'm proud of and was never really "addicted" to it. I quit cold turkey. Only smoked 5-6 a day with somedays being worse than others. I can honestly say after about a month of stopping, my lungs, body, and everything else felt 100% better. I had alot more energy too. I'm wondering if chewing is more addictive than smoking... I'm thinking it is.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
