What is wrong with life in the city?

It is almost 4am in the morning and I am still wide awake. I tried playing games on my laptop, that usually put me to sleep. I tried reading but the minute I dropped the book, I am awake again!

I would not believe myself if I would to tell myself I miss Battambang! But I miss Battambang. I miss the routine, the gardening, the children, the teachers and the friends. By 8 pm I could hardly open my eyes! Here I am, struggle to sleep and sleep does not come.

What is wrong with this life style? I have been out the whole day, I should be tired by now. Is it too much excitement? too much sugar? too much munching in between meal?
