Please invent this: phone-breathalyer

There should be a feature on your phone that stops u from making drunk phone calls and text messages. I'm thinking something like a breathalyzer, which would require u to blow into your cell phone BEFORE your allowed to phone or text people. For example, lets say your going out to your roommate's birthday dinner and you know by 11pm you might be leaving "god, I wish I hadn't said that" voice mails on your Ex from Texas's cell phone or shamelessly text flirting with your roommate's friend you met at said roommate's birthday dinner after he leaves. The cell-breathalyer would engage at 10:45pm, thus preventing any morning regret. There should also be an option to disable. No one wants to blow into their cell phone at 2pm while at work. Other options would include:

• settings which allow the user to call/text specific people (even if you've had one to many, aka bootie calls)
• once user fails test, block incoming calls from specific people because you know you'll say something hurtful/desperate/untrue
• hold text messages in que until the morning when user is sober and can react relationally
• If user blood-alcohol is way over, phone would shut-down completely.
  

I think I may have something here....
