I actually did a macro for iron jaws.
/macroicon "iron jaws"
/ac "iron jaws"
<wait.14>
/e DOTS <se.7>

This way I hear a little ping (that only i can hear) at just the right time when it's time to use iron just again to refresh my bites.
It works for me because I don't have to pay as much attention to the timers.
