"Hold on there kemosabe. Alcohol isn't a carb :^)"

Yes it is. It's carbon, hydrogen, and oxygen, (C2H5OH) just like all the other carbs, and it is far more harmful to a diabetic than sucrose.

Well it's been awhile since I took physiology but (dusting off the old textbook) "Carbohydrates are water-soluble molecules that contain atoms of carbon, hydrogen, and oxygen. These molecules usually have twice as many hydrogen as oxygen atoms, the same ratio of hydrogen to oxygen as in water molecules (H₂O). This ratio is easy to see in the molecular formulas of the carbohydrates glucose (C₆H₁₂O₆) and sucrose (C₁₂H₂₂O₁₁)"

While alcohols are "OH group attached to a saturated carbon". As your example shows, alcohols can have a very different hydrogen to oxygen ratio.
