Silence the sleep

  We all know about caffeine and what it does to sleep. Hence if you want to wake up early you should drink coffee, but u can't do that while u r asleep can u ? But the caffeine in the coffee is capable of fighting the sleep.
  So I present u all the concept of the Alarm Pill. Caffeine (or its substitute) should be packed in a pill. This pill should be such that it will melt completely only after say 6 hours such that caffeine will be released in us only after 6 hours (maybe 5 or 4 hours as required by the consumer). After the caffeine is released in us in 15 minutes it will reach our brain and voila we will be wide awake without an alarm.
  P.S. Just don't chew up the pill.
