"Hedonic" and Hedonism should be defined differently. The semi-last paragraph gives a good point to what Hedonism is.
"That is why the real Epicurus – in contrast to the crude sybarite invented by his detractors – denounced the rapidly rotting fruits of dissipation and excess. The constant pursuit of intense pleasures will in fact backfire, according to Epicurus, because it leads to the psychological hell of enslavement to unsatisfiable appetites. The would-be hedonist must take care to ensure that the pain of overreaching desire does not ruin his peace of mind and thereby defeat his original aim of securing a balance of pleasure over pain."
