Wt57 is right. There is no "tapering down". That is just a marketable, although innacurate, terminology. All it actually does is prolong the agony. There is one fact: to beat this thing, and addict will first go through withdrawal symtoms. The duration of those withdrawal symtoms is strictly up to the addict.
There are two options:
1. Quit cold turkey. Research shows that nicotine will be flushed from your body in about 72 hours.
2. Use patches, etc that promise a "taper down". Dependent on which method or brand that is used, this can take weeks or even months. Your body will inflict some form of withdrawal symptoms on you for the entire duration of that process. Then, in the end, at the very core of that system, you still have to eventually take that last step to completely stop using nicotine. At that point, nicotine will be flushed from your body in about 72 hours.
You do the math. Either way, you will have to suffer that 3-day period. WIth option 2, there is just a whole lot of suffering prior to that. And, by the time you get to the end of the "taper down", you could be posting double or triple-digit numbers for your days quit. Quit cold turkey today so that your bodies can immediately start the healing process.
I've tried, but I can't resist commenting on your opening statement. The word "considering" indicates that you are not yet committed to saving your lives. You probably already know how tough this process is. The only way you will be successful is to be 100% comitted to quitting. It has to be the foremost thing in your lives for at least the first month. Getting the correct mindset was half the battle for me.
I'm not trying to be tough or difficult, I'm just very passionate about what the nicotine addiction entails. I'm proud of my quit and hope to see you posting roll today. NOTE: you can't post roll here until you are completely nicotine free. No taperers can post. Reach out if either of you have questions or need any help. Assistance is only a PM away.
