Hi momo, welcome aboard.
You've gotten some great advice already. If I understand you correctly you are currently using NRT? With this in mind, I would like to encourage you to examine your feelings about cigs. It's true that stopping nicotine causes a few physical symptoms in the brain, particularly as described by Bakon above. But with you still using NRT then the majority of what you are feeling should be psychological.
Education, Allen CARR and this forum can totally help you with that but for now I urge you to think about this addiction. The truth is (well my truth at least) that I absolutely hated smoking. I was ashamed of it. It made me feel dirty. It lowered my self esteem. Every time you think of your 'loss', you have a choice. Either you reinforce your loss with thoughts of 'I'll never smoke again' and 'I miss the 'ah' moment' or you meet every negative/sad thought with (said in happy voice) "I never have to smoke again!" "I am free" and use the opportunity to reinforce your quit. At the end of the day, you have the power to make this quit easier or harder if you embrace the quit and every crave with positivity. Eventually, with the help of the educating resources available here, you may even believe it!
I wish you lots of success and a beautiful quit.
