I wake up at 6AM every week day morning utterly confused about why my cell phone is ringing. For the past 4 years, every morning as I wake up, I look at my cell phone and think to myself "why is this going off so early?"
I thought I would get used to it.
On the other hand, I spend each and every night struggling to fall asleep, drifting between being completely awake and aware of not falling asleep and restless sleeping during which I constantly dream of not falling or being asleep. I can literally count the number of nights when I fell asleep quickly, without going through this torture.
