Wake Up! Pro, an alarm clock program designed for insomniacs such as yours truly
Edit By BS Editor: Wake Up! Pro, an Alarm Clock program designed for insomniacs (such as yours truly). The reason I created it is because it takes a lot to get me out of bed sometimes, my three alarm clock can all be shut off... One day (on which I overslept) I came up with an idea: to use my PC as an alarm clock that would not let me go back to sleep. Written in Visual Basic 6, WUP can be a harmless clock on your desktop or a relentless noise machine, according to the options you select.
The following is a list Wake Up! Pros features:

Up to 100 alarms that can be set to go off every day or only on certain days of the week, or only on set dates.
Option to require a shutoff code (that makes you think as soon as you stumble out of bed, rather than sleepwalk and hit ENTER habitually).
Optional LOCK feature can make it really tough to end the program and go around that pesky code, he he...
Unlimited snooze... if you want. Disabling snooze button after 2 uses more fun, though!
Error Trapping can Prevent you from accidentally setting alarm for 8:00 ***PM****. (that was a close one...)
Use any .WAV, .MP3, .WMA, AIFF, or MIDI file as your alarm tone and/or use your computers internal beep (with varying volume or duration). Wake Up! Pro can change the sound each time an alarm sounds so you dont develop a tolerance to one sound (keeps things fresh).
Quick Set alarms can be set in a few seconds and delete themselves automatically.
Hourly chimes can be turned on/off by alarms and customized to play certain sounds at certain times of day.
Different view modes (Slim, Panel, MAX), colors and fonts can be customized. Switch views with Ctrl+(number)
Store view settings with up to 98 user-settable view presets.
Format the onscreen time and date several different ways.
Pop-up messages can remind you why youre being brutally nagged out of bed sooooo early!!!!
WUP can Chirp once every 20 seconds after you shut off the alarm, just to make sure youre... you can free download Wake Up! Pro 2.5 now.
