I'd say after 32 days, go for it. In moderation, a li'l sauce is okay for most people.

You are correct about the vodka, same for gin, rum, whiskey and other distilled spirits. Mix it with a low carb mixer, and you're good to go. It can put you temporarily out of ketosis, but not the way junk food would - your body can't store the alcohol the way it can store glucose. You should be "back in the pink" the next day.

The usual disclaimers: (a) almost guaranteed, your tolerance has gone down! Be careful. (b) Drink LOTS of water. It dehydrates you. (c) It can disrupt your blood sugar levels the next day, so be sure to keep an extra tight rein on the carbs.
