Well, it really depends on the individual. But for me, surely there are narcotics which work fine without making me tired or taking away my mental clarity. Oxycontin, for example, works wonders. There are plenty of options to be tried, as long as you have a sympathetic doctor.
p.s.: ritalin works fine for helping you stay sharp while on opiates and may even help boost pain killing effects. this nowadays is often seen with bad eyes but there's a study in which they demonstraded huge improvements in life quality for those on huge amounts of pain killers due to terminal cancer. i specifically mention ritalin because of this scientific evidence.
