Crazy time of my life, tried a ciggy and enjoyed it, provided an escape. Then I didn't smoke for many months when suddenly one day I just started jonesing for a smoke bad, so I had one. That happened for 1-1.5 years, once I left home one of the first things I did was start smoking. Tried quitting more times than I can remember, eventually the "need" for one just drives me insane and I'm right back at it.
Don't start! I know many people don't have issues with quitting, but I consider them lucky in that. Truth is you won't know whether quitting is easy or difficult, so trying it is a huge gamble not worth taking.
