My eyes are wide open again today...

I had 2 coffee coupons that I had to use by the end of September. One for Mega Coffee and one for Compose Coffee, used them amicably. Drank one while walking during the day, and another while reading in the afternoon... ... ... ...!!! Seriously, my eyes are wide open but why can't I sleep.. 😭😭 This happened last time too ㅜㅜ I guess it's because of my shift work, it's been hard to fall asleep at night lately. I have to work starting at 9 AM tomorrow(?), I'll be half asleep. This is bad. I should at least keep my eyes shut tight. Maybe that will help me sleep.. 😴
