Christmas Eve quitting is awesome. I picked that day too - 3 years ago. If some lame dude like me can do it, you can too. You won't believe how good freedom feels.
By the way , when craves happen, remember... Today you are winning. After thousands of days of losing. The craves, the fog, the pain... This isn't what life will be like going forward. What you are going through us sooooo worth what is ahead.
If you need a number or if I can help - shoot me a pm. Proud and honored to quit with you today, sir.
