So what do you guys recommend for a very heavy sleeper? Used to have one, but never woke me up (not enough vibration)
I use iPhone under pillow on vibrate.
See I can sleep in the light no problem... I do not wake up with just a standard light... Yes the sun is free, but if it doesn't do you any good then its not working. I've tried the flashing light clocks, and those don't work for me, I just turn over...

I guess your body isn't understand the UV and probably you required an unhealthy energy drinking or something to keep you wake up!
electric shock apparatus attached to your toe, and the clock being direct across the room.
LMK, I can make you one. Can't guarantee health safety though.
