If you are going away on vacation from work, make sure you have some down/transition days at the start and end of it. At the end of vacation, having a day off between vacation and starting work will make it easier to begin your work day. Likewise at the start of your vacation, having an easy day after work but before travelling should make it less stressful and tiring for you.
I did not do this on a recent vacation I was on. I went from a busy week at work and home right into travelling for my vacation. I still went out after arriving at my destination and it was enjoyable, but I was also exhausted by the end of the evening. Likewise I arrived home on a Sunday evening and went to work the next morning. Again I managed it, but it was hard to shift from vacation mode to work mode. In both cases, a down day at the start and end of my vacation would have been good.
As well, have some down days in your vacation. It’s tempting to schedule non-stop activities for your whole time away. If you can manage it, fine. But try and have some low key days mixed in there. You may find your overall vacation more enjoyable that way. I did.
It’s tempting to sprint your way through from work to vacation and back to work. For short trips, that may be fine. For longer trip, pace yourself and give yourself permission to do low key days, especially at the beginning and end.
