I had too much sleep this evening, even if I haven’t read through the Nephrology conotes for the second time and there are just less than 2 days left. I don’t know why I felt so tired after my dinner. Did I have too much exercise this afternoon? Or, after that, I didn’t take off my sweating clothes and take a shower immediately, so that I caught a cold?
In the about 3 hours sleeping, I woke up several times, but fell asleep right away. I tried not to sleep so long, because my private teaching cancelled temporarily, and I have to use this extra time preparing the Nephrology exam on Thursday.
Maybe I shoud feel happier that I finally get up, and I must try to use the night time more efficiently.
