After Monday and Tuesday, where I felt really quite good, yesterday and today I have been back on the tired side. I have been a little stressed out with client projects, which has ended up taking over my evening time as well, so that may have something to do with it (and of course still getting used to only 4.5 hours of sleep a day). I am still hopeful though that this schedule will work, because I am getting a great amount of productivity out of it.
