When I quit about 7 years ago I went cold turkey. I went nuts for the first few weeks then had the same symptons you are going through. They would come and go. I didn't start on the cigars until about 3 years ago. I dont crave Cigarettes at all but back then it was tough. I can still remember like it was yesterday. When I would have a coffee or finish eating I would reach for my pocket where I used to keep them without thinking and then realize what I was doing. It was at that point I would get stir crazy and then it would pass. Hang in there and be strong.
