I need to do this!

This will be my 3rd attempt at quitting, I've given up before for over 2 years and have no idea why I started again, it just happened it was just one and then next thing I'm back smoking again and I hate it and how it controls my life.  My last attempt (3 weeks ago) failed miserably and I know now where I went wrong and how I can quit for good.  I need to do this for myself, for my health and having that extra money won't hurt either!
