How can you wake up at 3:00 without using an alarm ?

Drink a glass of water before going to sleep.

Listen for the trains coming through town, they start up about that time, if I don't have the a/c, a fan or some other white noise going they wake me up and I live 2 miles away.

Easy! Get a pet. Particularly a cat. The cat speaks louder.

My cat takes care of that.

Why would I?

By sleeping at 2:59

After I use an alarm clock for a couple of days, I start to naturally wake up a few moments before it goes off.

Snoring dog usually works, lol

Tell your friend to call u at 3.00
