Analyzing nicotine addiction

I've been smoking cigarettes since I was about 16. Back then it was a once in a while thing, but within a few months i found my self smoking about 3 a day. So far this year, I've been smoking packs in 2-3 days, which has definitely been hurting my health and my pocket. So this month I've decided to try my first attempt at cutting back on smoking by never buying a pack anymore, and after day 7, I found myself only smoking like 1-3 a day. Eventually I'll completely quit but this experience has shown me that i'm not drowning in a nicotine addiction because if I was I would have already bought a pack. This is day 7, and this experiment will continue.
