6:35pm. Too late for a little coffee?

Depends what time you want to sleep and what you need to accomplish. I'd say drink some water and get to bed at reasonable hour. Not even to the weekend yet.
Typicslly I would agree. Also, every day of the week is the same for me.. And my son will be visiting here soon. Staying for spring break. Very special occasion. Usually I am ready for bed by 8.

Coffee tastes better at night.
I feel that. When I was 20 or so, I drank coffee primarily at night with friends. Of course I typically slept like 4 hours a might back then. Sometimes I can sleep right after coffee anyways. Just depends..
Half-life of a coffee is 8hrs. No bueno
I always have an espresso after dinner no matter the time. It’s good for digestion
