I'm around 31 or 32 days as well and I've been getting some pretty intense sugar cravings, which is weird because I never eat much sugar. Most of the time I don't give in to them because I don't keep sweets in the house. Occasionally I will have a small amount of dark chocolate and one night i had a couple donuts, which I later regretted. I'm not sure when they will go away but I just try to ride them out or eat a more healthy snack like some almonds or peanut butter.
