I fixed 1 and 2, dunno how to fix the last 2.

3) The if's look to be checking the same things a few times, so can be re-structured to not re-check so many times.

4) Unless you've got code after this, why are you doing an extra 'if' within the while? It's superflouous.

if ($me != tired) { return } | else { echo -a Get a pot of coffee now $+($me,.) }
