It is normal. Our alcoholic bodies do not process the mass quantities of the sugar we put in it in the form of alcohol like normal people's bodies do.
Do not load up when you feel the craving. Try and avoid processed sugars. Get it from fruit or fruit juice instead....The kind without added sugar.
If you need a quick boost of sugar try a hard candy and let it dissolve slowly.
Your pancreas may eventually get back to normal.....but in the meantime don't feed the beast like you did with alcohol.
Moderation.....introduce and consume it slowly....and avoid processed sugars.
This too shall pass.
