Stephen, you CAN do this! Your attitude is totally awesome! Yes, it is very much a mental addiction as well as physical. The best way to go into this is to keep a positive mindset!! Think about all of the pros vs. the cons. The pros always outweigh the cons!! For me, it was a matter of life or an early death, since I was beginning to play with fire (literally), after 39 years of smoking. The phrase I use all of the time, whenever I have a craving is, "Smoking is not an option." I know that if it is not an option, then there is nothing else to think about period! Also once you actually do quit, cravings are a wonderful thing, because it meanst that your body is getting rid of poisonous toxins!! Keep doing what you are doing and you will be set to go!!
