I've always wondered why they don't build alarm clocks based on sleep cycles? We sleep best in 45min REM cycles, and waking up in the middle makes you feel groggy. When setting the alarm there should be a dial that has sleep-cycles printed on it, and you turn the dial to select how many you want. The clock will read what time the alarm would wake you up as you select each setting. Select as many cycles as you can get, while still getting up on time. Then simply tell the clock how long you take to fall asleep.
