When I am not sure. I found a stressor that I could not get past and have been smoking today. Soon I will reset and get back on board. I am numb at the moment, but know once this passes I will be kicking myself for turning to it. Have I gotten anything from smoking. A headache, but that could be from the crying. I am choosing to allow nicotine to comfort me. My husband who had his last cigarette August 6th after 50+yrs of smoking passed away this afternoon. I will be around and I will quit again soon.
