School means you can't smoke most the time anyway. So the times in life when you know there is no smoking will most likely be the same. Like being on a plane, you know you can't smoke so you just stay busy and time goes by. Just stay busy during the break times when you would have smoked. Do something different that makes you happy but you couldn't smoke doing, and the coolest thing will be no perfume needed after that break smoke. Bags of hard candy worked for me and still does. Happiness is a definite key, joke with yourself or whatever it takes to STAY HAPPY. Nicodemon loves depression.
What I have done is kept myself in the places where I wouldn't have smoked, that took the cravings away or postponed them. In the beginning it's all about time and safely getting to the next moment. The more of those moments you stack together the closer you are to calling it another day quit!
My last quit started with NRT but realized that it was postponing cleaning the nicotine from my body (3 days), so after the first week or so I stopped it and just sucked on candy or gum. Kind of hard to smoke when you have a mouthful of candy....
Some things kept me busy also was looking what others wrote here during their early days, gives you some comparisons to your own feelings.
Wish you well.
