I am a sugar freak.
I'm a sugar addict.
I have the worst sweet tooth on the planet.
I was a real sugar junkie. I don't think I realised I was actually fully addicted to it.
I have an insane sweet tooth.
Sugar is more present in America or England than it is in France. I think there is an addiction to sweetness.
My guilty pleasure is sugar.
I had an addiction to sugar growing up - major, major, major.
