Adjusting your brakes manually will give you a temporary fix. Your rear end is designed to be self-adjusting. Take a look here: http://auto.howstuffworks.com/auto-parts/brakes/brake-types/drum-brake2.htm to see the basic functioning of the self adjustment mechanism. IMO, I'd opt for the cure and not the band aide. Done once and you're GTG.

Added: Some self adjusters rotate when the emergency brake is set. If you haven't been setting the ebrake, it's possible that could be the issue.
