Congrats on quitting! I'm not a smoker, but one suggestion would be for you to take your "pain is weakness leaving the body" signature and use it as a mantra any time you're craving.
My mom quit smoking cold turkey after 25 years of addiction. She was a mess for a few weeks, but fought through it. Now, 10 years later, at 51 she's a healthy eater, a member of a gym and exercises 5-6 days/week and in great health right now. Eyes on the prize--good luck!
