The Christmas season brings with it lots of merrymaking and in spite of less drinking happening overall  and the availability of many zero alcohol products, many of us will be getting drunk. And soon afterwards, many of us will regret it. Surely the answer is simple: to avoid a hangover, just drink less? Alas, that is easier said than done. Alcohol’s inhibition-reducing effects can undermine the steeliest resolve.

All to discuss with Professor Luke O Neill , Professor of Biochemistry at the school of Immunology, Trinity College.
