I bought a second hand alarm clock on eBay the weekend before last and it arrived today, hooray! It uses light instead of sound because I can't stand alarm noises. Now I can finally ban my phone from my room!
@Marshall Yes. I always wake up several times before the vibrate goes off on my phone anyway, thanks to the traffic and wildlife noises, so the light is a backup. It's mainly going to be there so I can see what time it is (I didn't have a clock in my room before).
