Good luck! You've made the first step, just deciding to quit! I quit about 2 years ago and it was def. difficult, but not impossible. Every time I had a craving I just tried to think of something else and get through one craving at a time. Having gum also helped me (with the oral part of it). It also helped me to know that the nicotine is completely out of your system within a day or so, so beyond that it's a mental addiction you have to get passed.
You'll also feel much better, smell better, and be so proud of yourself!!
