Partner, this CAN (no pun intended) be done. I am the biggest nic addict that I've ever encountered. Quit over a month ago after 31 years of EXTREME dipping. If I can go through day three, ANYONE can!
Day 3 sucks, I know and I'll never forget this. Embrace this. These first few days must be embraced. Acknowledge what this horrid plant and drug has done to you, your family, your fellow man. Spit in its face. Do it.
The day you forget day 3 during your quit is the day nicotine will reclaim you. Day 3 is your STRENGTH long term. Own the suck, my friend. I am with you. Quit...for today.
