It is difficult sometimes to wake up in the morning and the only thing which helps to fight with drowsiness is coffee (mainly coffeine). To solve this problem I want to introduce an idea of constructing a device (which is stuck to to an arm, leg or chest during sleeping time) that would inject the same caffeine in a calculated amount intravenously or intramuscularly at a certain time (say, half an hour before the desired awakening time) so that the awakening process would be much easier and faster.
