I found in those times I did "quit", well for a while lol
What made it easiest for me was looking back not forward to get through the cravings.
After that first 24/48 hour period had passed (the impossible stretch lol) i'd just think back when I felt like one.
> "I went through yesterday I didn't have a cigarette and the day passed on by just fine".
And also the reminder - that if I gave in and had a cigarette it would all be over in a few minutes and all it would do it is reset the nicotine cravings in my body all over again.
I also used to smoke "ghosties" I must have looked like a freak lol
Basically like smoking with nothing in my hand just the hand movement and the breathing lol
