I quit over 20 years ago also. The first year I would dream about smoking. It was the same dream but in different locations. I would suddenly realize I was smoking a cigarette and panic. I would grab my shirt breast pocket where I carried my pack, and squeeze the pack in an effort to see if it was full. This was an attempt to discover how long ago I had returned to smoking. As I would squeeze the pack in my pocket in panic, I would be relieved to realize that I was just dreaming. That sudden feeling of relief was turned to joy as I found that I could smoke in my dreams! It was wonderful! I could smoke in my dreams and I knew I was dreaming! Those went away after that first year. I wish you well with your emphysema.
