Naltrexone works by reducing cravings and the pleasurable effects of alcohol. All the person has to do is take a pill daily. The person doesn’t need to change any other behaviors or quit cold turkey. It just makes people want alcohol less.
The person doesn’t need to be a total train wreck to get help. It has been prescribed for “hazardous drinking”, which affects about 670,000 of us. Talk to your GP for more info.

That’s really cool, things like this should be more known as there is still a big drinking problem in NZ. Though I guess for most people the first bit is realising they have a problem.
