Heavy Head

Not sure why, I feel that my head has been quite heavy these few days.

Monday/Tuesday/Wednesday, heavy head until I went to sleep early.

Today was not so bad. I don't feel it as heavy as past few days.
Yeah, but don't say my head is big ok. :P

Maybe using my brain too much these few days.
Troubleshooting and problem solving can be fun, but can be drainy too.

It's late. Time to sleep.
Need to make it lighter, and lighter, and lighter ...
