Jack describes his insomnia:
"Forced to remain in bed all day till 5:00pm owing to sleeplessness last night. All sorts disturding thoughts re war, people at home, Hut Pt. party etc. keep coming to one during night and can’t discard them from my mind. And it’s such a loss of time too, having to be in bed in an attempt to get some rest. However will just have to grin and bear it.”
