The first, and most obvious help for this problem is to not drink. But, many will not us this as option while out and at parties. So having a designated driver is the second best option-this way you know there is no chance the driver will have had too much to drink or not enough time to metabolize what they did consume.
Another solution is to be very cautious about how much you drink. Try and limit yourself to just one to three drinks during the night, depending on how long you are at the party. Allow yourself time after your drink before you get behind the wheel of the car as well.
If you are able to, another great option for parties at friends homes or in big cities is to stay where you having the party. If you are at a friends home, make plans to stay if you know you will want to drink. If you are at a big city party, rent a hotel room for the night (just make sure you don't have to drive from the city party to the hotel!).
I have included some alcohol metabolism charts to show just how little alcohol it takes to be over the legal limit. Above is a chart for how many drinks you can consume at different weights and what the blood alcohol level would be. Below shows what counts as one drink:
Please be careful! It is winter and on top of worrying about drivers having too many drinks, the roads can be slippery, icy, and snowy as well.
We hope you go out of 2012 with a great time, and welcome the great possibilities of 2013!
