Having an irrational arugement...

So I'm sitting at my desk... and all I can think about is a cigarette... I've gone online and read and read and read,stop smoking, I've posted on other's posts... and now I'm just jonsing for a smoke.. I know I can't have one... I won't let myself.. its not for me anymore, its for my baby... but right now its all I can think about.. I've taken deep breaths.. I've sucked on straws.. I've had a drink and I've snacked.. and now,quit smoking, all I want is just one cigarette... day four... day four.... not gonna have one... I'm not... but I'm also not rational right now!!
