One of the things I learned from reading up on biphasic sleep is that it's ok to miss a nap now and then. Compared to the (totally insane) schedule of polyphasic sleep where you constantly nap your way through the day, it seems reasonable. It's just ingrained in me from my youth that you're not supposed to nap. As a friend of mine commented, "mum always said that sleep during the day will make it difficult to sleep in the night". True, to some extent, but we're just shifting things around here.
So, on the third day I sort of missed my nap.
Being my own employer means that I have varying working hours. Most of the week I work with clients in Stockholm, which is approximately one hour away whether commuting or going by car. (1,5 hours during rush hour or when leaves on tracks prevent Swedish trains from running properly)
