Well i quit smoking cold turkey over 5 years ago.  It was the hardest thing i have ever done in my life.  I don't want to smoke cigarettes again i remember the coughing and hacking that i went 
through with them, and the issues my wife went 
through with asthma and other issues.  Plus i have a 2 young boys ages 2 and 3 that i would not want to submit to the dangers of second hand smoke.  So the traditional light em up smokes are out of the question.
My situation is this.  I have gained a tremendous amount of weight in the past five years.  And i have come to the conclusion that i have an oral fixation.  I am not hungry, i simply want something in my mouth (i hate gum with a passion, so not an option).  Probably a problem that carried over mentally with 10 years of smoking....  I recently had a fellow class mate bring an E - cig to our Creative Writing class and found it profoundly interesting 

  I have been trying to research into all of it and WOW so much info....  Tried getting opinions from people on Facebook and didn't get much back... 
So i guess the big question is Nicotine?  Is it a bad idea after so long to introduce it back into my system?  I read *a little about even non nicotine e - cigs?  I need some advice?!?!    HELP!
