I had trouble sleeping the night before, I had to get up around 6am and went to bed around 3am and tossed and turned until 5:30am before the alarm went off I finally fell asleep but yeah that was a waste. I should have realized the number one thing to get me to fall asleep instantly is to set my alarm to go off 15min after going to bed, to simulate that feeling of having to get up in the morning hehe.
