I'm glad you have decided on freedom from this crippling and deadly addiction C12 What Jim said is the truth. Quitting smoking is a choice we make and once we do we NEED to be FULLY committed to our decision. You know already how ugly things can get in the early days of your quit. That's why being fully committed and taking smoking off the table no matter what is so important. So is sticking close to the community here daily, at least for the first while and reading/watching everything you can while you're here. You will learn valuable things from the experiences of others who were at the same stage you are right now.
Please don't expect the worst of your withdrawals to end suddenly on day #3 because you are not using any NRT products. Yes, nicotine will be out of your body sometime around day 3 but, you will not have had time to train your brain to live comfortably without smokes by day 3. This is the bit that takes the longest time to adjust to. Weeks, yes, even months of gradual adjustment of your thinking about smoking. How long did you smoke for? Probably years I would guess. During those days, you brain was making connections between smoking and all sorts of other life activities - stress, joy, sadness, boredom. The list is almost endless. It took years for you to develop those associations when you smoked so .... guess what? It will take a while to readjust your thinking to what it would be if you had never smoked in the first place.
Stick with us here and let us help you along. It's free and will probably be the best decision you ever make for yourself. Education is the key to quitting , along with unwavering self commitment and a bunch of other quitters like us to lend some support
