Am having headache recently. I think its cause by my lack of sleeping. Its hard for me to fall asleep at 10pm. I dont know why. I guess I want to cherish every minute of me waking up. Do u get what I mean. No eh. Who cares. I also think my headache cause by pre-menstruation too. Pity me. Hopefully I recover fast so that I could have productive day at office. Go away headache.
