That was the end of my observing session for that night but I didn't have
any
trouble being sleepy for that 1 hour late night drive home.

This is what I worry about most - sleepiness on the drive home. I try and
keep a little coffee in reserve, but it doesn't always seem to do the trick.
Anyone have any tips?

Water works for me. Lots of water; keeps you hydrated, too. Discovered this
decades ago and it still works when I need to pull all-nighters.
