It varies like crazy for me.
I’m an insomniac, and some nights after being up for a while, I’ll fall asleep again within an hour of the alarm. Those days, I struggle to focus enough to sit up, and force myself to move in a minute or two.
Other times my eyes will flick open and I’ll be in full awake mode almost instantly. Some of that was trained behavious from when I was on-call.

Speaking as a guy approaching 60, I say get in touch.
It iis so easy to lose friends, and increasingly harder to make new ones as we age. Hold onto those who knew you best. Maybe some won’t survive and maybe you’ll become closer friends with those you didn’t know that well, but make the effort, and do it now.
