Peeing 15 times a night

I always stop drinking liquids by 7pm because I pee so much at night. I lay down at 9 after going to the bathroom and will get up 3-4 more times before falling asleep. Most nights I get up 4-5 more times before morning but tonight and on other nights I've been up every hour, someone's 2-3 times per hour  - total tonight is 15 trips to the bathroom and its only 430 am. I'm so tired - I just want to get tonsleep.  Anyone else pee this much or is something wrong?
