When will the sugar cravings decrease?

This is my fifth week of drastically reducing my sugar intake. Last Saturday, at the crayfish party, I ate a small number of candy pieces, a piece of blueberry pie, a piece of chocolate cake and drank two cans of Sprite (not Zero). Also, I made sure to drink about 33 oz (1 liter) of water. I haven't had a headache since Sunday last week, which means hopefully I'm not hypersensitive to white sugar.

In addition to this, I have also been careful with my protein intake and have not cheated a single day. So far I haven't noticed any improvement when it comes to my vertigo but on the other hand it hasn't gotten worse.

To improve my sleep, I have started taking magnesium as a  dietary supplement. It can take up to a couple of weeks before you notice a difference and I'm on day three so so far I haven't noticed anything.

Despite all these changes, I still have a massive craving for sweets.
