If you pursue it by means of drink, you are forgetting the hangover. Epicurus pursued it by living in congenial society and eating only dry bread, supplemented by a little cheese on feast days. His method proved successful, in his case, but he was a valetudinarian, and most people would need something more vigorous. For most people, the pursuit of happiness, unless supplemented in various ways, is too abstract and theoretical to be adequate as a personal rule of life. But I think that whatever personal rule of life you may choose, it should not, except in rare heroic cases, be incompatible with happiness.
