First month free of nicotine, 31 days without cigarettes

It is now 1 month since I last smoked a cigarette and it will be the first of many, there are certain moments during the day that the craving for nicotine appears but after a few seconds it flows away. The cravings dissapear faster when somebody is smoking nearby, the smell of cigarettes is really bad, as a smoker you never smell it like when you stop smoking, it is terrible. I am still running but I have to slow down a bit because I start to feel something in my knees, I don´t want to force it, I have all the time in the world, the most important thing I had to do I did and that was stop smoking.
