It is very common, and it is also common for a sober for quite some time alcoholic to end up being diabetic. Our sweet Carol D was and so am I.
I suspect that deep down you are concerned about his health a bit also. Many alcoholics upon finding recovery become hypoglycemic during the first few years and until they know they are, they get that 'craving' for something sweet. I was hypoglycemic for over 3 years and kept a jar of dry roasted peanuts in my vehicle, in my desk at work, a baggie of them in my purse for when at meetings and definitely in strategic places in the home (quick protein).
It balanced out and for many years I could take or leave sweets. Then I started to get cravings again, and ended up with the diagnosis of diabetic.
So, it would not hurt to quietly suggest to AH to maybe see his Dr to make sure he isn't hypoglycemic.
Other than that, Anvil beat me to what else I was going to say, lol
Keep posting, let us know how you are doing, as we do care very much.
