If so, then Google has the answer for you – Mail Goggles. A new feature released from Google Labs (if enabled) will ask you a few simple mathematical questions (which supposedly seem difficult when intoxicated) before sending the email – to save you from the embarrasment later.

Go to Settings in Gmail and click on the Labs tab – then scroll down and you’ll find Mail Goggles:
Simply enable it and each time before you send an email through Gmail it will ask you some mathematical questions which need to answer correctly in a limited time before the email will actually be sent:
Although, I think those that are adament about sending that email while intoxicated will either grab a calculator or find the settings tab again to disable it.
