[Edited since my initial post]
I looked up & read the guidelines: warning - only quickly though. Accidents are included in drinks per night, but at their cutoff risk of +1.0 deaths per 100 drinkers above non drinkers the guideline would still have been 2 SDs a day.
I'd encourage others to go to this link. I intend to read more fully. It seems to me that for truly informed judgments anyone would have to understand their risk benchmarks: see Appendix 5.
Provisionally, the value judgments looks conservative ("risk averse"). The Apendix 5 tables indicate the the extra DISEASE (not accident) deaths across a lifetime drinking 4 SDs five days a week is +1.5 deaths per 100 drinkers. I was unable to quickly understand the non-drinker baseline: for instance, was the mortality rate for included diseases already 1 or 5 lifetime deaths per 100 persons?
Would like others to look at this & I don't guarantee my interpretations. But on my current read, I'm OK with 98.5/100 [women: 98.0/100] chance that four SDs five times a week will NOT cause my death from alcohol-related disease. In actuality, more than 3 SDs an evening & my sleep patterns are materially disturbed anyway. Might adopt a goal around 3 weekdays x 3 SDs + 2 weekend days x 6 SDs. And I'll encourage moderation by buying the best I can afford consistent with budget & target SDs.
I'll be monitoring my other risk factors ongoing. Also, alcohol-related accidents do matter - but that risk is quite age, sex and drinking location dependent (home is safer for drinkers, if not spouses unfortunately).
Hope this helps. John
