Howdy, neighbor. I'm in Johnston County, right around the corner from you. I trust that since you are "tarheel done" that you are a Carolina fan? If you're not, I'll still quit with a State fan. If you're a Duke fan, you're on your own. :)
Noticed your question about sleep. My first good night's sleep was after the dull headaches resided at about day 20. Over the next 60 or so days, I probably slept like a baby about twenty percent of the time. There is no answer to it other than your body's nine systems (muscular, nervous, circulatory, etc.) are completely rewiring themselves to accept the fact that they are getting healthy and aren't sure how to react. You're a newborn baby in that respect. So am I. I'm three and a half months old.
Quit for YOU first. Quitting for your kids is a hell of a perk, though. They'll thank you later on when you tell them what an idiot you were.
Look at your inbox. I'm going to PM you my number. USE IT if you need it. I'm paying it forward. That's what we do here. Quitting is totally worth it, dude. I quit with you every damn day.
