Concentration is probably the first thing to go, right?

You've hit the nail on the head right here.

I find when I don't get enough sleep, my concentration levels decrease. The good ol' "You have an error In your SQL syntax; check the manual that corresponds to your MySQL server...." comes more often than not. When all It Is (example) Is a backtick, single quote or opening/closing parentheses omitted In a given SQL Statement.
