Tips for diagnostic actigraphy?

I’m starting my 7 day actigraphy to test for IH (>660 min sleep over 7 days). I know it’s rather rare to do one of these. I won’t be taking off of work, but my job is pretty flexible so I can dial things back for the next week. I’m worried that I won’t sleep enough since I’m used to forcing myself to half-function with <10 hours a night. Anyone else been through this and can offer tips on how to handle it?
