That's amazing, I'm happy for you. Like you said, it IS possible. I was a daily smoker for 10 years but I quit cold turkey. It was not easy at first but as the time goes by, it becomes a routine. I tell people to always get really busy during the first months, preferably engaging in physical activities. Also, one relapse doesn't ruin the whole effort. I am a non-smoker for 6 years now with a few relapses. Never been happier.
Keep up with the good work!
