Great choice, Seth! And thanks for your service. You can do this. Quitting is done one day at a time. Don't think about tomorrow, next week, next year or whatever...we'll deal witht them when they get here. All we need to focus on is getting through today...this five minutes. And anybody can go five minutes, right?
One quick word about the "this is gonna suck" attitude. Like anything else, your attitude will largely determine your success. Don't feel bad...almost every new quitter has that attitude. Let me suggest that you get tough and turn the tables on the Nic Bitch. How? Realize that everyday of freedom is reason to celebrate. Think about the night before Chrismas? Did you think, oh man tomorrow is gonna suck? Hell no you didn't. You were pumped. And all you probably got was a bunch crap you didn't want...you know, socks and underwear?!!
Now, you're now giving yourself freedom. You're getting your life back. If you were excited about socks and underwear, you should be fist-pumping in the air about this. YOU'RE FREE!!! You are calling the shots now.
Yes, you'll have a headache, constipation, sleeplessness, anxiety, etc. Those are reminders of the miserable prison cell you made for yourself. But they are also the feeling of healing, brother!!! Do you want to go back and get in your cell? FUCK NO!!! Nobody gets free for the asking....you gotta earn it. Embrace those symptoms...they are the first steps to your new life of freedom!!!
You got this. Just post roll, read all you can, and repeat. You can do this, brother!
