Is there a scientifically based opinion on a way of drinking alcohol that minimises the risk to health. i usually drink 12 - 15 units / week but have gone above that in December. Is Dry January actually worth it if i then go back to the previous number of units. Would it be better to cut down the number of units as of now - eg to 9 - 10, and stick to it long term. Anecdotal information may be useful but hard facts would be better.
