Another option would be to have an entire event sheet dedicated to your debug events and include it in your main event sheet - then remove it before export. I like doing it this way as all debugging systems are located in one place.
*Edit* Although re-reading your OP, I see that you're specifically concerned about forgetting to turn it off. If that's the case, stick to Wacky's suggestion.
He could add all the events related to debugging below a specific group.
And use "is in preview", to enable or disable that specific group.
On the other hand, best practice would be to not forget it :P
