generally everyone tried if before once they work...rite? but it's not really good for your health.Our mind is like timer, we have a schedule in our mind to tell us when to eat, when to sleep, when to take a nap, when is your most active and resting period.
when u dun sleep for 24 hours...you wont feel tired during your active period, but you'll force yourself to continue working during your resting period...(in that certain period of time, you'll feel very very tired...heart rate increase, less sensitive to enviroment, lost of concentrations..)
after you went tru your resting period( which is equal to your sleeping time=about 6-7 hours)...you'll go into your usual active duration...in that certain period of time, you wont feel tired anymore (due to hormon secretion increase). However, you'll lost probably 30-70% of your usual performance...vary on individuals.

So, the next time when u comes to your resting period, you'll feel extremely tired...because you like making debt to your sleeping time...
usual sleeping period could exceed more than 30-50% of your usual slepeing time.

insomnia is kinda disease from medical view. sign and symptoms to another related disease one most often.
try not to take sleeping pills...(which most of the people would)
i would strongly recommend you to see a doctor...
