IMO, the whole sugar alcohols thing is terribly misleading. Here's the bottom line:
* They ARE carbs, and they are carbs that get digested (unlike fiber which goes right through)
* They don't cause insulin spikes in most people.
So it comes down to why you're counting carbs. It if it's about keeping your blood sugar stable, then you're probably fine now counting them. If it's about limiting carbs to lose weight, then they should be avoided.
I also totally understand about being caught in a rush and not wanting to go totally off plan. I keep single serving packets of almonds and beef jerky in my car, just in case.
