Help to quit cigarettes?

I am going back to school as a juinor in 15 days. I have been smoking for 4 years now. I want to get new freinds, ones that dont smoke. Does anyone know any methods on how to quit. I have heard pop a peice of gum and chew like crazy when you get the urge to smoke. For me I know im not addicted to the nicotine because the nicotine gum didnt make me feel any better. Im pretty sure its the act of inhaling and exhaling the cigarette. Any advice, websites, strategies would be very helpful. Thank you all in advance for helping me overcome this nasty addiction!!!!
