I am so wiped out I had to call in sick tonight. I felt really guilty (even though I called 4 hrs ahead of shift). Ii am new to noc shift,just started again a few weeks ago.I was doing fine the first 2 weeks.I basically keep the same schedule on off days.Is this extreme fatigue normal? I never felt this on days even though physically the day shift was more grueling and insanely paced! Will I feel like this forever,or is this my body trying to adjust? Thanks.
