Habits can change in days or weeks.  It doesn't have to take long periods of time and lots of angst.  It takes knowing what you want instead of what you're getting or doing, changing your mindset and changing behavior.  Awkward to do this for most who use the old "will Power"but considerably easier and faster using self hypnosis and a couple of behavior mod ideas.

 Maybe I can share some ideas that can work for you.  Watcha got?
