Feck. I passed out while browsing online just after 4pm. I'll wait until 11pm and go back to sleep so I can wake up early tomorrow. At least I don' feel sick anymore now I have had some sleep/
Sometimes I have trouble sleeping because I'm lazy and get no physical activity to tire myself out. My solution: I'll stay up way to late, sleep like five hours a night, then on my days off, I'll crash and sleep for like ten hours. It seems to be working well for me.
