I had energy drinks and now i can't sleep?

So I had 2 monster energy drinks(large can) at 8:00 pm , it is 3 am and I haven't slept a wink and I feel like throwing up, I think I'm just going to pull an all nighter now, because I have to be up by 6 am, but is this normal or should I seek medical attention it was my first time having energy drinks, I feel tired but I just can't sleep. I have nothing important Like work or school tomorrow it's just a bummer that I can't sleep, I will never ever touch an energy drink again, is this normal though cause I'm panicking a little
