Binge drinking is an American epidemic. Nationwide, people die from binge drinking on an almost daily basis. Sadly, this issue is a personal responsibility issue, but for some people, keeping track of your drinking becomes difficult with the consumption of alcohol. Thankfully, technology has advanced to the point where there are affordable personal breathalyzers on the market that you can use to monitor your inebriation. I do not intend for you to use a breathalyzer to go out and make sure you can drink more than everyone else. It should be treated as a way to better monitor your personal responsibility for your drinking habits. 
Most of us can safely say we are good at monitoring our drinking habits. There are many who lose control also. Considering the issues of drunk driving, domestic violence and many general crimes, knowing that alcohol was involved should change the general public consensus on the stuff, but that does not happen.
Alcohol is heavily ingrained into our society, from the earliest parts of civilization. The personal breathalyzer is a tool that allows those who are more lax in there monitoring of their drinking to ensure that they are safe and do not endanger others with their drinking. It is hard to understand for people who do not drink, however. I only wish to say that for someone who is a binge drinker, or an alcoholic, that there is an inability to control their intake and it costs them dearly in many aspects of their lives.
Despite my own personal enjoyment of the occasional beer, or glass of scotch, I know that alcohol is a poison, and when ingested in large quantities, causes myriad physiological complications that I would rather avoid.
