i think that drug... what's it called, it's an antihypertensive i think - that was found to be useful for nullifying emotions attached to traumatic memories, that would probably work equally for pleasant emotions and let you experience the wonder again
for me, re-reading tends to end up being a "oh, wow i didn't notice that before, i didn't notice that before" experience so maybe you should get the book out and read it again
i had to read Human Action twice just to grok it adequately, but i bet i'd see a shitload more things that i now understand better due to experience and further study
