I can't remember ever seeing a house down here that was built that way. On the other hand, I have seen plenty of commercial structures that were built like that. And now that I think of it, alot of those buildings didn't even have plaster on the inside. They just sealed and painted the cmu.
As long as your utility bills aren't outrageous, I'd say don't mess with insulating the walls. In one of my home remodeling books, they give a list of insulation projects ordered from most cost effective to least cost effective. Insulating existing walls is the very last item on the list, because it is generally quite expensive to get inside them. Now, I agree that you should take a look in your attic. If there isn't sufficient insulation, it would be fairly easy to add more.
