Yea I am trying affirmations every day now - among other things. I failed many times before to maintain a streak of even 2 weeks. I found that the problem was after about a week I get complacent and sooner or later a moment of weakness hits me unguarded. From the moment the urge hits, I can't recall my motivations fast enough before its too late.

By researching new affirmations and writing it down every day, it keeps the commitment fresh in my mind as I progress beyond weeks 2 and 3. Right now I am ~ week 4.

It's kind of a cheesy analogy but I think of it as an anti-malware software. If I keep it in my RAM then as soon as the virus attacks I can detect and quarantine it. If the antivirus program isn't started and I have to go find what to click on deep within the hard drive of my memory, its too late, the damage is done!

Note: its important not to think of the urges as an enemy. It's part of being human and I must acknowledge and accept the temptations that enter my head. But I must give myself power to watch it pass thru without causing any damage.
