The best thing you can do is NOT sleep through the day, Even fi you stay awake all night, force yourself to not sleep during the day.
Teenagers actually don't produce the hormone/chemical that makes you feel tired or go to sleep until much later than younger and older people, so that already puts you naturally out of synch.
What sort of sleeping pills did you have? Were they prescription ones?
Doctors often prescribe two types of tablets to people with insomnia. The first are ordinary tablets which just to happen to have a very high rate of drowsiness as a side effect. Often doctors will prescribe a tiny dose of an antidepressant with this side effect, and this will make you sleep easier.
If this does't work however, then they'll probably go on to prescribe you real sleeping tablets. Now because these are so addictive, and cannot be taken with alcohol and a number of other medications these are a last resort. They tell you to NOT take them everynight, and rather to use one to get yourself back into a routine.
So yeh, go back to your doc and ask him/her to reconsider whatever they've given you.
But the best thing I can recommend is just not sleeping during the day. I know it's really hard, but it will get you back into a normal sleeping routine.
