Why did I ever start???

I took up smoking at 26, had never smoked before.  I had birthed my two sons & figured that my lyf & my lungs were my own.  I smoked for 11 years & usually smoked between 30 -45 ciggies a day.  I have watched so many of mates struggle with quitting. I have two sons 15 & 13, my 13 year old especially has been at me to give up for quite some time now.  on Monday 7th May I woke up & decided that I didnt want to smoke anymore, I had two open packs, one in the car & one at work, they are gone now, my partner smoked them.  he still smokes at home, in our home.  I decided to quit so i did!  I dont think I will go back to smoking - I am enjoying the extra money in my pocket to much lol - i am not normally a motivated, follow through kind of person but I QUIT so can you  xxx
