Lethargy strikes

Yesterday evening, and even up to this very moment, I feel like staying at home on my bed and sleeping the entire day. It's been a while since I felt this lethargic. I went to bed and instantly fell deep into slumber that I forgot to turn off my television & laptop (plus feeding my fish in Fish tycoon), and brush my teeth. I didn't even hear my cellphone ring. This coffee jelly frappe didn't even help my current situation.
