I have been told I have an overactive bladder, and at bedtime I have to get up 9 or 10 times to urinate, is there a certain position you can lay in bed and get more sleep, plus I am a 23 year old girl and the hospital doctor wants me to calendar my last three days at the toilet plus how much it was e.g. ml or oz whatever is on my bottle, and to write everyone down on my so-called calendar, what do I put underneath me if I am sitting on the toilet seat, it will all go down the toilet?
