Will I be able to wake up for school...?

If I took 7 Dramamine pills (350mg of dimenhydrinate) around 9-9:30 pm. I wake up for school around 5:35 am. I weigh about 122 pounds. Last time I took some, I took 5 pills (250 mg). I took them on the weekend around 9:30 pm. I fell asleep around 10:30-11 pm and woke up around 6:30 the next morning; I was so tired that day. It was a weird feeling, very lightheaded, almost dizzy, really relaxed.
