When is the most time that you crave a cig?

Number one Trigger for me is definitely stress. If I get upset angry or getting ready to snap I tend to smoke before getting rational. Or if I already became rational I smoke to calm my self. It is a very bad and nasty habit. I have quit a few times cold turkey it is very hard. I am in the process of trying to quit again and find it very hard because of the stress in my life right now is not helping.
