Before midnight

It is around 11pm now. But I thought it was almost midnight when I sat at the desk and I was about to give up on writing today's diary.
Now I know I still have one hour　left, I feel relieved.
Today was a hot day. I sweated　quite a bit and changed my clothes several times. I drank a lot of tea . It made me sweat and go to the bathroom many times. I made one liter of iced tea this morning and I drank it all up before noon. Then I made one liter of iced coffee.
Now I am drinking some iced coffee to keep myself awake, but I can't keep my eyes open.
I should go to bed.
