Those of you who know me well, know that I sleep heavily. Like the dead, only more so. I've slept through a tornado, several wild parties, smoke alarms, an attempted break and enter with my dog barking...you name it, I sleep through it. People trying to wake me have actually thought I was dead.
Right now, I use an alarm that starts with the radio and graduates to an annoying beeping, and the television programmed to go on shortly after the alarm starts. The blinds are open so I get sun in my eyes. This combo works most, not all but most, of the time.
Recently I purchased an alarm clock guaranteed to wake the heaviest sleeper. You put it under your pillow or mattress, and it vibrates and buzzes. So, I put it in my pillow, thinking that close to my head was the best location.
Didn't work. I slept through it. Soundly.
So I returned it, and caveat emptor to anyone else who tries it. Good luck, hope it works for you.
Is there a Rube Goldberg-type in the world who could invent a mechanism to dump me out of bed into a tub of cold water when the alarm rings? That should work...I hope. *LOLOL*
