I'm a diabetic, I drink and make myself beer that I like. The key is
2 servings. That was one of the hardest things I had to do. The worst
part is that I all a beer judge and 2 servings is tough to do.

With proper diet management, a diabetic can eat or drink almost anything.
IMO a diabetic asking for a "Special" beer may be not following
instructions from their health provider.
