> Off caffeine, a proper nights sleep will have you up and active right away.
This is not universally true.
I've experienced mornings in four different cases. Chronologically: drinking lots of soda, dropping caffeine and taking Adderall, consuming basically no stimulants for a year or so other than the occasional soda once or twice a month, and drinking black coffee and/or green tea regularly.
They've all been universally pretty awful, with still an hour of snooze button needed at most, but caffeine by itself has been the least bad both for mornings (including compared to no stimulant consumption) and in terms of overall side effects.
By far the worst regular day-to-day experience is the caffeine+sugar combo, though. If you can tolerate your caffeine without sugar, it can be quite nice.
(The worst absolute experience is a cold-turkey dropping of amphetamines for a weekend to reset a growing tolerance. Be prepared to watch a lot of TV, eat a lot of cheetos, and have very little desire or ability for serious thinking.)
Assuming you wake with an alarm, the biggest impact on how you feel when you first wake is where you were in your sleep cycle. In deep or REM sleep you will feel lousy.
