Best Tip i can give you...Have 2 alarm clocks (trying gettin one with an annoying buzz or the likes)/radios, set them within 15-20 mins of each other (or as appropriate, but not same time) and keep as far away from bed as possible. You wake up first time, turn first one off, and if ur like me you go back 2 bed, when 2nd one goes off, u get up to turn it off, look at the time, and the panic of getting late to work/college/uni kicks in, waking you up.
