I have to say i was exhausted after day 2. That was one tough day especially considering all the hours i had to work. The good news is that i slept well for about 9 hours. Pretty broken sleep actually, 2-3 hours at a time but i didn't have any problem going back to sleep again after i woke.
So i've changed shifts at work, working midnight to midday now. This is half way through my 3rd day already. I'm expecting this day to be easy, i hope i'm right.
