I'm taking a break from January 1st (My friend's b-day) to January 20th (My b-day), not only for tolerance but to use the money I'd normally spend on weed to save towards getting a kief-catcher.

If you just want to drop tolerance, I'd just break for 4-6 days... breaking for more will do something, but it's not enough from what I've been able to to make a difference. For you, however, it might.

In the end, break for however long as you want. Nothing wrong with not smoking.
