i used clean cigs I bought from crest @ 9.99 for the kit plus 7.99 for 5 refills and a lot of will power....31 days and counting.
It would be a lot easier if you had a good personal vaporizer that satisfied your cravings and was something you enjoyed using. Take the money you have saved on cigs and get yourself a basic eGo kit and a clearomizer like a kannger EVOD, Mini cartomizer tank or a Vivi mini nova.
This set up is a basic eGo battery with a Vivi nova tank (1.8ohm atomizer) and a "beauty ring" from a Kanger protank.
