Alarm clocks that will sell

  Version 1:
There should be voice recorder in it, in which we (or our family members) will record a message before going to sleep of to why we were supposed to wake up at that time. It is required because I often decide to wake up in the morning to do something but it doesn't strike me as I switch alarm off and go back to the sweet sleep which has an amazing command over my thoughts and action at that time.
  Version 2:
How about having a water ( or a substitute ) spray which will fire at our face from all sides just after 5 minutes of alarm ringing, I bet that the memory of getting wet will hit our subconscious mind (just as it does at time of a calamity of the dangers) and we would be wide awake.
