I have been thinking quit hard about this lately. I sometimes wonder if the addiction to nicotine is stronger psychologically then physically. When they started to prohibited smoking in certain areas I remember that I memorized all the locations that you could smoke. They funny thing was that when ever I would walked past these places, they I really wanted to smoke. I could spend a most of the time without even thinking about cigarettes, but once I walked near these places all I could think of was having a cigarettes. Do es anyone else feel the same?
