When you go out to drink, you may feel completely sober after one or two bottles and decide to drive. But when NTSA stop you and unleash their Breathalyzer kit on you, it makes you wonder how you over the limit after such a small consumption.

Well, worry no more. First of all, if you’re going to drink, DO NOT DRIVE. At all.

But if you don’t have the luxuries of getting a designated driver or can’t afford a rideshare, you can wait for the alcohol to leave your system.

Using Drink IQ can help you map out how long it would take to get sober based on the alcohol percentage of your beverage and how much alcohol you’ve consumed.
