 About an hour after starting his sleep shift , Borman obtained permission from ground control to take a Seconal sleeping pill . The pill had little effect . Borman eventually fell asleep , and then awoke feeling ill . He vomited twice and had a bout of diarrhea ; this left the spacecraft full of small globules of vomit and feces , which the crew cleaned up as well as they could . Borman initially did not want everyone to know about his medical problems , but Lovell and Anders wanted to inform Mission Control . The crew decided to use the Data Storage Equipment ( DSE ) , which could tape voice recordings and telemetry and dump them to Mission Control at high speed . After recording a description of Borman 's illness they asked Mission Control to check the recording , stating that they " would like an evaluation of the voice comments " .
