I'd sooner trust my decision to send a mail, than my arithmetic ability

You gotta love it. I would use it! haha

This wouldn't work for me. I'd just disable it and continue having have a meltdown anyway.

A lot of times instead of the math questions...I could use a non-disabling feature that would queue my messages for about six hours before actually sending them, and have the ability to delete them when I came back to my senses.

I once sat on a particularly shocking text for over 6 hours. That was hard to do, but I was proud of the response.

Stamp out drunk e-mailing now!!
