stop smoking - smokefree for more than a week already 
good for you, m8! You taking any medication or doing some activity to help with the addiction and habit breaking?
I got a nicotine inhaler and was able to kick a pack-a-day habit pretty easily. Gum and lozenges killed my stomach, and I imagine patches would leave my hands unoccupied and wanting a cigarette. Having something cigarette-like to puff on every time I had a craving was great. It's a passive inhaler with 2mg delivered cartridges that load into a thing that's sort of like the plastic tips on swishers.
I would recommend it to anyone trying to quit. The only caveat is their price: I think 160 cartridges was like, $300+ dollars if you paid cash, plus a doctor's visit to prescribe it. Mine was free courtesy of Los Angeles County. Check your state, city and county (or whatever the equivalent is where you are) as a lot of them have free or really cheap smoking cessation stuff. A lot of states have a 'quitline' program (google it) which provides free patches and 'counseling'.
Does nicotine inhaler removes nicotine in your lungs?
No, it just supplies nicotine with no smoke or other irritants/carcinogens. It sort of circumvents the withdrawal symptoms from nicotine and lets you battle the psychological addiction by itself, which is the real hard one to kick. Once you don't feel the overwhelming compulsion to smoke, kicking the nicotine alone isn't too difficult since you can ween yourself off it.
