You are doing great! The absolute worst physical part is behind you. Once you pass the psychological it is a piece of cake from there! OK, that is somewhat of an oversimplification, but it does get much easier.
I had to quit cold turkey due to an emergency spinal fusion. I was committed to the quit because of the surgery but I had the added problem of making sure my mind was in the right place to quit for myself.
Make sure you practice deep breathing when a craving hits. It helped me to close my eyes, relax and think of being in a pleasant place. After only 2 to 3 minutes the craving was gone and I felt rejuvenated.
I agree with the last poster, do not count your hours, days, weeks, months, at least not in the beginning. After I passed the 3rd month, I began counting so that I can track my success and money saved. In the beginning my mind was thinking of how long since I SMOKED but after I got over the hump, I began thinking how long I had been SMOKE FREE. There is a big difference.
On the 52nd day, I hit a wall. My psychological craving was in overdrive. That, luckily was when I found this board. These wonderful members talked me through and within 10 days I felt like a new person. I have had some very minor cravings, like doing something routine and go to reach in my purse for a cigarette. I have to just laugh at myself, I really do have CRS.
Remember to reward yourself! An easy way to do it is play yourself each day the amount you would have spent on cigarettes (or each payday). Once you have reached a milestone, you have a fund to pay for your reward, or save up through the year and take a really great trip.
Welcome to your life as a non-smoker, it really is much brighter, smells and so much better.
