I had fine first half of the day, slept well, felt alert and a little more creative than usual. Now I woke from the nap and I'm feeling pretty tired again. Neither of my naps have been full 90 minutes during the first one I woke up about 70 minutes into sleep and got up and this time I woke after like an hour. I did continue sleeping before my alarm went of. Both times my nap has felt really shallow sleep, like I'm semi-concious all the time.
My dream recall has taken a severe hit in these starting two days, but besides the naps and it, there haven't been any other problems so far. I haven't remembered one dream in my four instances of sleeping so far.
