I've been a 3+ pack a day smoker for 35+ years. Haven't had a smoke for 45 hours.

Just an update.
I'm going good at 84 hours now.
Had a stressful day with work, and the camper, and the kid.. and held fast.
Woke up last night at 2 AM with weird chest pains.. like my lungs were on fire. Got back to sleep after some pacing, deep breathing, and chugging some water. Then dreamed of smoking.. woke up with a start at 4:30.. and no I wasn't smoking, lol. Coffee time and more pacing then, lol.

And all of your well wishes and stories are helping me, and for that I thank you all.
