That happened to me last night (I picked the middle option by the way, not one of the disgusting ones in the thread!!) Was one of those nights....couldn't sleep, then needed the toilet, then the cats started fighting, then they brought a mouse in. I think I've had about three hours' sleep :/
Anyone have the same with brushing their teeth? I often make the mistake of getting into bed first, and then I really can't be bothered to get up. Force myself to go anyway, or else I wake myself up in the middle of the night.
