Quit Alone.

I think quitting with your one of your mates is a terrible idea, Partnership never works when it comes to quitting. The chances of you collapsing is always there at the beginning, why double it, coz if u see your quit buddy smoking back like a chimney, you WILL say, what the heck' and laugh it off. And you'll end up  silently regretting upon the moment... dont do it... For once stand alone... and you should be just fine... 30 days and counting.... lol
