Doesn't it have a buzzer/radio function? Radio static, like I mentioned, usually works great for me. Actually it works a little too well, when I first figured out that it worked I put it up almost as loud as I put the buzzer on, and it almost gave me a heart attack a few mornings cause it sounded like a nuclear warhead was launching nearby...

Either that, or my friend has an old school clock that's shaped like an army general, and it starts yelling and cursing at you till you wake up. You might be able to find one of those somewhere. If you do, tell me where, by the way, cause I want one of my own.

Other than that... develop a system based on strings and pulleys and small white lab mice that will trigger at a particular time of morning and dump a bucket of water on your head. Good luck remembering your dreams let alone who you are after that happens tho.
