I am those people like sleep very much..... even the fire alarm can't wake me up!
However, I don't know why.....I wake up everynight around 2:00am, for almost 2 weeks. I went to the kitchen for having food! If not, I can't sleep.
Then, my husband worry about me.... and take me to consult the doctor .....and find that I was 懷孕 for 3 or 4 weeks (i.e. I know I was 懷孕 before the time for M comes.....)
=>食得訓得玩得 from the begining of 懷孕
