When my UC was at it's worst it was impossible to get sleep due to colon waking me up every couple hours.
It's the inflammation talking to you. Your doctor is a dope if he/she's never heard of this symptom. It's very common.
You need both rectal enemas and better meds to control the inflammation. Also an OTC sleep aid wouldn't hurt, it can't overcome UC, justs helps.
