One more question for all of you that have successfully quit... how many days passed before weren't focused on getting through and being strong each minute? I am super proud to report that I haven't touched one in 72 hours. I truly thought the first 48 would be the hardest, but let me tell you, today really wasn't easy. I was a real closet smoker (after the kids and hubby left for school and work, before the kids got off the bus, after everyone went to bed), and those times are just so difficult. The yearning doesn't go away in just a few minutes. I guess I really thought today would be a bit easier, and I'm disappointed that it wasn't. I don't want this to be my focus anymore!!
What's generally going to happen the first day you quit smoking is that you won't necessarily crave a cigarette except as a habit; you may feel less focused than usual and less alert.
Within the next 24 hours after that, you cravings for nicotine are going to become very strong and you will be very tempted to begin smoking. Hang in there, because your body is ridding itself of nicotine, and this takes about three to four days altogether.
The third day may be the worst, whereby you are simply going to want to smoke and nothing else. You may have difficulty focusing on anything, including work. Constipation and excessive coughing are also symptoms of your body ridding itself of nicotine, as your body adjusts to not having it.
By day five, you should begin to feel better and your cravings should be less. You should begin to notice that you can breathe better and that your ability to smell and taste food will begin to return to you. These are things that usually disappear, largely, when you smoke, so you'll begin to enjoy the fact that you don't smoke because you've got these two senses back.
After about the fifth day, your physical withdrawal should be pretty much complete. You'll begin to notice that you "feel cleaner," that your teeth are brighter, your skin is clearer, and that you won't smell so strongly of smoke. These are all beneficial effects that will help make staying away from cigarettes easier.
Although the physical withdrawal from cigarette smoking is pretty much done by the end of the first week for most people, the psychological effects of smoking are very strong as well, and those cravings may not ever go away entirely. You may also begin to notice that your appetite will pick up significantly after you quit smoking, which is one reason why so many people gain weight after they quit smoking.
