I quit cold turkey for over 2 months. I felt great etc but when I had started a new job, everyone smoked. There would be days I would end up in a bad mood and eventually just caved in and started again. Now it's been harder then ever to quit and I regret starting again :S I'm on hopefully my last pack right now and I'm gonna try to kick the habit as I want to focus more on paintballing and actually saving money.
