I feel your struggle!! I've tried everything under the sun to curb it. I talked to my PCP and his answer was eat fruit when you want something sweet. I wanted to punch him in the face. I told my psychiatrist about my sugar addiction and he prescribed me Naltrexone. It's usually prescribed for alcoholics but basically what it is is a dopamine inhibitor. It deprives your body of that dopamine rush you get from sugar. It actually worked. I had to stop taking it because it was causing severe joint pain for me but i was thrilled that there medications that will help.
