Hello,
I stumbled across this:
5 Reasons To Take Naps at Ririan Project
Does anyone of you practice this midday 30-40 minute nap? I have very often this problem with sleepiness after midday, but when I have the chance to take little nap, I usually just sleep 2 hours straight (it's probably this slow-sleep) and when I try to wake up after 30 minutes I feel even more sleepy. Second problem is that when I do sleep during day it really messes up my sleep rhythm, which is usually 8 hours per day, from 10pm - 6am, at nights I just don't fall sleep.
Actually from new year I'm thinking of trying out polyphasic sleep, because then I start working from home and I don't have to do regular office hours, I sleep and work whenever I want to.
Anyone has experience or suggestions with this?
