Smoking

I've only smoked one day in almost two weeks. I was with my sister and we simply do not get along, it's no excuse but I was stressed and needed something to keep me from becoming a complete bad word... I felt bad that night, not just for giving in but my body in general just felt bad. Not having a cigarette actually isn't that bad, I've found the only time I truly have craved a cigarette was the day I was with my sister. Other than that I don't really feel like I need to have one, in fact I'm starting to wonder why I've been smoking in the first place. 
No one told me to quit I just felt it was time, I don't smoke in my house or my vehicle and I can't smoke before or during work because I work in the health care field. I didn't smoke around friends who didn't  It seemed like I was honestly only smoking when other people who did smoke were around and maybe once outside before bed, but that usually left me with a horrible taste in my mouth when I'd wake up the next morning. I just decided it was time to not waste my money anymore.
