For when you’ve only had 2… 2, you say

Ever been at a party or whatever, and found yourself only using one eye because people look like this?

Here is the newest addition to gmail: Mail Goggles

The idea is that if you are trying to send an email at a certain point in the night that you pre-set, like between 12AM and 6AM on the weekends, you will have to complete a series of 5 not-too-challenging math questions in under 43 seconds.

If you are unable to do that, then you are probably a little too drunk to be composing and sending emails.
