An alcoholism treatment with an 80% success rate using naltrexone taken before drinking to block endorphin highs, popular in Finland but little known in the US, UK, and Australia.
"It's called the sinclair method. You take a targeted opoid blocker called naltrexone only one hour before drinking and it blocks the crazy endorphin high that alcoholics get. You still get a pleasant relaxed feeling without that need for more and more to chasing the buzz."
