Timing of PIO shots

How good is everyone about doing PIO injections at exactly the same time every day? And thoughts on being a little flexible here and there? I’ll be traveling tomorrow with my husband and my normal shot time is mid flight (from west coast to east coast). Better to just do it a few hours earlier? And then over the wknd stick with my usual 8pm ET or move it to 8pm PT while there? My husband and I will actually be there for a week. I have a call into my nurse but curious to know what your clinics have told you and your experiences...
