It's all a head game. If you tell yourself it's going to be difficult, it's going to be difficult. If you tell yourself you will do it, you will do it. It's entirely your decision to make, and in the end, you alone are in charge of the outcome of your quit. I will tell you this, though. A common thing people say after they've been quit for a while is "I was worried about THIS? Why didn't I quit sooner?"
Speaking of making decisions, why don't you make the decision to flush whatever nicotine products you have down the toilet today? I'm being as serious and literal as a person can be. Lift the lid, put that SHIT into the toilet it belongs in, pull the handle, and quit TODAY. Not the trash, either. The toilet, so you can't dig the can back out later like I and hundreds of other people did when we "tried" to quit. My hands were actually shaking when I took the step of flushing my stash. I was nervous and afraid of what life without dip would be like. But, I made that decision 185 days ago and haven't regretted it since.
If you are resolved to quit, truly resolved to quit, there should be no problem in starting today. Withdrawal won't suck any less on the 21st, or New Year's, or Christmas, or any other arbitrary date people set. Withdrawal will suck less when you battle through it. If there's anything every quitter on this site understands, it's the concept of "I'll quit when..." Some of us vowed to quit when a child was born, or New Year's, or when we met a wife, or started a new job. And yet we somehow managed to push the date back. Hell, I pushed quitting back for 13 years. Every other day there's a person on this site or in the chatroom who sets a quit date, then are never heard from again.
These people set quit dates, too. Look how well it worked out:
Almost Quitter #1Almost Quitter #2Almost Quitter #3And it goes on and on like that. Post once or twice, then gone like a fart in a whirlwind.
Think about this. If you quit today, by the 21st you'd already have nicotine completely out of your system and you'd be well on your way to establishing a life of freedom. The worst part of withdrawal would already be behind you. Your heart rate would have normalized, your mouth would begin to heal, and your sense of taste would have been virtually restored to what it was. Think of quitting like pulling off a bandaid. Do it all at once, let it sting for a brief moment, then move on with enjoying life. No need to drag it out.
We'll be here for you when you're ready! I really hope you'll consider not postponing your freedom.
