On LessWrong, or on blogs by LWers, advice has been given on how to become bisexual, or polyamorous.

However, there is no advice on LessWrong for how to stop liking something. Yet there are many stories of people having great difficulty giving up such things as video games and internet distractions. It seems to be easier to acquire a taste than to relinquish it.

All the advice on resisting video games and the like (internet blockers, social support) has been on using tricks of one sort or another to restrict the act, not the desire. Even when experimenting with specific deeds, it is easier to try something in spite of aversion than to forego it in spite of attraction.

Are there effective methods of ceasing to enjoy some activity, or of refraining from enjoyable things? What presently enjoyable activities would you use them on?
