My biggest craving occurs at 9:30am each weekday. That is the time my wife leaves for work (I work at home). Since I feel foolish driving my car away just so I can smoke (refuse to smoke on my property or in front of anyone), I would leave right after she left for work each work day. Each day, the personal assistant in my brain who reminds me when I am forgetting something starts calling me, reminding me that I ALWAYS go smoke at this time. And when I don't, it creates a visualization for me to remind me who much I would enjoy taking a deep drag. So 9:30 when my wife leaves is my biggest craving of the day.
I'm going to go do some hanging leg raises right now to distract me (that and this typing).
Anyone else have a time of day it most strongly hits them?
