"This rousing sequel to the classic Ringworld continues the adventures of Louis Wu and Speaker-to-Animals on that fantastic planet."--School Library Journal
Robert Heinlein, Joe Haldeman, and Issac Asimov are some other heavy hitters in this space.
The science fiction novel "The Ringworld Engineers" by Larry Niven (1980) features one Louis Wu, who at the beginning of the story has become a 'wirehead' (wireheading being "the act of directly triggering the brain's reward center by electrical stimulation of an inserted wire, for the purpose of 'short-circuiting' the brain's normal reward process and artificially inducing pleasure.") He manages it by use of a specially designed timer which requires several hours of painstaking work to reset.
He only disconects the droud because he knows he will die from starvation, dehydration and atrophy if the doesn't go through the motions daily. But every moment without the droud is existential dread.
"How much intelligence does it take to sneak up on a leaf?" - Larry Niven (The Ringworld Engineers)
