judging but what you are bored by, i would suggest staying away from "a portrait of the artist as a young man", but you might like some other stuff by Joyce. Kerouac is great, i would try "on the road". i know you don't like some more off the wall shit, but Cuckoos Nest is amazing. Irvine Welsh: can't beat Scotish writers. try the classics as well: Beowulf, Iliad, Odyssey, aeneid, Gilgamesh, et c... and of course Walden by Thoreau, doesn't fall into your list of "similar" books, but still amazing.
for the lazy people who don't want to rad all the stuff i wrote:
Joyce, excluding portrait
Kerouac, on the road
Kesey, cuckoos nest
all epic poems
Walden
