Why are you doing this? This drug is extremely liver toxic. I'd get to a doctor right away and get my liver checked out, and stop taking this drug at high dosages if you want to see 17.
Please visit the emergency room immediately. The dose you took is a toxic level, and could cause major medical problems.
I agree with people above, go tell your parents and visit the ER, doses of any medicine this high isn't got, stop taking it and visit ER.
I hope you'll be okay.
