From Section 8-3 of the Apollo 8 Mission report: "When the Commander was unable to fall asleep 2 hours into his initial
rest period at 11:00:00, he took a 100-mg sleeping tablet, which induced approximately 5 hours of sleep described as 'fitful.' Upon awakening, the Commander felt nauseated and had a moderate occiptal headache. He took two 5-grain aspirin tablets and then went from the sleep station to his couch to rest. The nausea, however, became progressively worse, retching occurred, and vomiting happened twice. After termination of his first sleep period, the Commander also became aware of some increased gastrointestinal distress and was concerned that diarrhea might occur."  The Commander's condition was described to Houston via a non-public data channel.

 CDR: "Crew status report here.  We're behind on water and food and we don't see to have much of an appetite.  We're trying to stay up with the water but the food is - not that there's anything wrong with the food - but we're just not very hungry ...  The CDR got 5 hours of fitful sleep and rest, and the other two people are trying to sleep now."

 CMP, first comm after sleep.  CapCom asks how he slept.  CMP: "Oh, you know.  The first night in space all the time; it's a little slow."  CapCom: "The old man woke you up earlier than he needed to."  CMP: "Well, we just couldn't sleep any longer."  LMP asks Houston for "an evaluation of the voice somments in the upcoming tape dump, which may be an effort to alert them to comments about the CDR's gastro problems."

31:40:49
 TLC
 CapCom asks the CDR for a "quick summary of how much sleep you got on Lovell and Anders."  CDR: "Jim had about 4 hours sleep and Bill had about 3 hours sleep  We feel pretty good today.  We would like to see, in looking over the flight plan - perhaps we ought to put the rest periods a little bit shorter and more frequent.  It seems it might work out better.  We got all out of kilter on it yesterday.  We are sort of trying to get back in a normal cycle."  CapCom replies, "We will look into that."
31:43:31
 TLC
 CDR: " Remember, the most important part of the trip occurs in two days when we start back (to Earth).  So you all better get rested, too."

 Crew status report.  "Each of us (LMP and CMP) has had two sleep periods ; Frank's in his third one right now.  Bill (LMP) had 6 hours the last time; I had 4 hours the last time.  Good to Fair, both of us.  Frank had 5 hours the last time, of fair.  And Frank, of course, is sleeping now."
52:52:40
 TLC
 CapCom asks if any of them has had symptoms similar to Frank's and what medication has been taken.  CDR reports nobody is sick and that the Bill (LMP) took a Seconal "last night".  Capcom asks again about how they are feeling in general, noting that, so far, the CDR has had about 15 hours of sleep and the LMP and CMP about 10 each.  CDR: "We all feel fine; we are going to fix it now so that we call have one more rest period before the LOI."  Ten minutes later, CDR says that the LMP took a Marezine and a Lomotil "when the doctors told him to."

91:11:02
 TEC
 CapCom requests a sleep report for their time in lunar robit and "your plans for the next couple of hours".  CDR: "We all only got about 2 hours sleep today, MAX(IMUM).  Bill's going to stay up awhile and Jim and I are going to sack out.  We're going to try to rotate short sleep cycles till we can get back to the normal one ... Jim is in a daze, and so am I ... Ken, tell the people, if you see anything getting close to the gimbal lock to be sure and whistle, too, will you?"  CapCom: "We sure will, Frank.  You will want to make sure one of you keeps your comm carrier on."
