....and?
Kidding. I know it can scare the crap out of you. But it really is just a craving.
They happen.
Before I quit smoking I read that nicotine cravings never decrease in intensity, but they do decrease in frequency. My father told me that's what he found. Patted his shirt pocket for his pack of cigarettes 15 years after he stopped. Out of an old habit.
I've found this to be true for cigarettes and alcohol; TBPO the nicotine cravings are worse and harder to ignore.
At this point they're an abstraction. Look, there's a craving. What's for dinner again?
