When I used to turn to cigarettes at work, I now turn to deep breaths to calm me down if I have a stressful moment. It gives me the same effect for the most part - minus the nicotine jitters. I won't say it has been easy, but I am doing well. I have been slowly and thoroughly going through my jackets and washing them to get the smell of smoke out of them. The only aspect I still need to get a handle on is eating when I feel like I can going to need a fix.
As I continue my life with PTSD, I will share my challenges and discoveries on this blog.
