Note: A paragraph similar to the one below appeared in a longer post, which I have divided into two (the other part is now called "Post Yom Kippur Encouragement for those Having Setbacks"). I lost the original text of that paragraph (Chaval al d'Avdin . . .), but below I have recreated it from memory:
If you're still holding strong after Yom Kippur, please do everything you can to stay clean until Sukkos. If you do, you will, b'Ezras Hashem, experience Simchas Yom Tov like you haven't in a very long time, and that can help propel you to be successful for the rest of the year!
