Apps to Prevent Drunk Texting, Dialing on New Year's Eve

Another option is the DrunkDialNO app that allows you to make a list of people you don't want to call while tipsy. There's no limit to the amount of contacts you can add to the no-call list, and you can set the block time for as little as one hour and up to 48. When you try to call a designated contact on the no-call list, you'll get a pop-up like the one here.
