Bests & Worsts Reviews from Amazon

I'm a heavy sleeper. Not the average "has a hard time getting out of bed" type but the type where I've been physically shaken and screamed at and not woken up. I've had firetrucks, ambulances, and police cars in my front yard and slept through it. A tree collapsed on my neighbors house and I slept through it. I sleep through my building's fire alarms. I've slept through gun shots in my backyard. Little to say, my phone's alarm just doesn't do the trick. I slept through classes for weeks at a time even though I had alarms going off for hours. And boy, can I sleep. I can and do sleep 17 hours a day when I can. Longest I've slept at one time was 23 hours and I only woke up because I was dehydrated. I spent more time asleep than I do awake (not by choice, I'm just tired all the time). This alarm scares the hell out of me every morning but it sure does get me awake. Only problem is remembering to set it every night but I'm getting used to it. Just make sure to put it where you have to get out if bed to turn it off so you don't risk falling back asleep.
