I recently had a collapse lung. It had nothing to do with smoking, it was a spontanous pneumo thorax. Being in hospital with a test tube for three days, I was unable to smoke. When I came out I still wasn't feeling well so I didn't smoke. Now it is almost two weeks and I had only half a cigarette and I didn't like it at all. The fact that your fingers smell and I don't feel good after. I feel like smoking, but whenever I see a cigarette I am disgusted. It took a collapsed lung, but I finally did it. (Yes) Wish everyone good luck, and I know it is hard.
