I think it should be more acceptable to have a nap after lunch. I can barely keep my eyes open. I've put some drawing pins on my desk to wake me up should I drop off.
I managed to fall asleep on the most uncomfortable bus ever this weekend, I'm convinced I can sleep, anytime, anywhere.

Anyone else struggle to stay awake in afternoons? I find the worst is in a meeting when my eyes go all googly and refuse to stay open or focus.
