Dark urine?

Ki

Hey, I was wondering why my pee has been super dark like this lately? It’s been a few days now. I’m not dehydrated since I drink bottles upon bottles of water a day. It began the morning after I accidentally took ten extra strength tylenol (I went to the ER, they took my blood and a urine sample and they said I was okay).

Sorry about the TP in the pic, gross. Ha.

Thanks.
