same here.. i can consume a caffiene ladened drink and go to sleep no issues.
Coffee actually works on me now I'm on stimulant medication haha
First day I was put on (low dose) stimulant meds I slept for 16 hours haha
Also, coffee power naps are totally a thing, I get a real boost if I drink a coffee and immediately lie down to sleep, then get woken up 25-30 mins later when the caffeine is doing it's thing. Definitely end up feeling better and able to concentrate deeper into the afternoon when I do that round lunchtime, compared to taking a nap without first having coffee.
It's worth noting, from a youngish age (15) I spent about 10 years working as a Baker, sleeping all sorts of strange hours... so I developed by nessacity the ability to put my head down and sleep no matter whats going on. Caffeine has never hindered that in me.
Coffee powernaps sounds wonderfull and totally logical. I might have to experiment with that concept!
