I quit after 10 years...... back in 2000, it was a millennium new years resolution.
Never looked back. Infact I still got a 10 pack in my car with cigarettes from the day before new years in 2000. I was kinda sadistic that way, although i never actually smoked again i did like having them around to test my spirit but after a year or two I totally lost the desire to even think about smoking.
I know that 10 years smoking damaged my health but I can say that my health has improved so much that its all been worth it and I know im better for having cut it out of my life. No-one needs that kind of burden because you know one day youll wake up with horrible sore that might turn out to be cancer and its game over. Who needs that shit?
I think this site really helped me form my philsophy and determination where concerns quitting and im pretty proud that my word did end up being my bond. If you ever feel weak, just read some of the info here:
