As I recall, sweet things like orange juice or candy are useful to ease cravings for alcohol in the early weeks of sobriety.
These days sugar is regarded as addictive, so craving sugar, not alcohol, may be a sign of sugar addiction. Once every couple of years I might pig out on doughnuts. The day after, as I drove past the doughnut shop, I noticed a slight craving.
I think it may be wise not to give in to those sugar cravings if you can. Health problems can come from too much sugar.
