Nikki I just want to let u know how happy I am that you have made this decision. My father was a smoker for 30+ years until he went to get some dental work at a dental school here in Houston and within minutes he had all the big dentist looking at his tounge. Well he was diagnosed with cancer then and there and he never got the dental work done. He has since quit smoking since that day, has lost half of his tounge (as that's were the cancer was), all of his lower teeth and has other complications as side effects of the chemo/radiation treatment he under went. And the worst part is he's not in the clear as the cancer can come back any day. You'll see in the long run that this will be the best decision you have ever made.
I didn't write this to scare u but to encourage u. When u feel like quiting and going back to smoking re-read and lift ur spirit up so that u can know that u have the strength and courage to quit smoking.
