Carbs are NOT bad. Actually, carbs with a low
glycemic index are GOOD. They help you keep your blood sugar stable.
And that's the goal -- to keep your blood sugar as stable (and in the right range, of course) as possible. If you're mostly "good" then the occasional "cheat" likely won't do much. But the worry I might have would be that the "better" reading the next day follows a spike the night before. Easy enough to rule out.
Then again, maybe you'll help them discover that sulfites (found in most wine and in Chinese food too, I think) act in lieu of insulin.

Ok, probably not.
Oh, and do you know about
cinnamon ?
