Taking your temp at the same time is important, but it should also be after 3 hours of solid sleep. So, when I work dayshift, I take my temp at 6am. When I work till midnight and get to sleep in, I still set my alarm for 6am and just go back to sleep after. When I work until 4am, I just let myself sleep and wake up whenever and temp, but I make sure to record the different time on FF so it shows an open circle meaning there was something that may make the temp not as accurate.
If you want the girls to be able to look at your chart, you can edit your signature in your profile and post a link to your chart
Good luck and hope your stay here is short and sweet!
