“ What does it do? said Loeser. You feel as if you're being sucked down this fathomless, gloomy tunnel. Or to put it another way, it's as if all the different weights and cares of the world have been lifted from your shoulders to he replaced by a single, much larger sort of consolidated weight. Your limbs stop working and you can't really talk. If you take enough then it can last for hours and hours, but it seems like even longer because time slows down. Hildkraut smiled wistfully.
