If a survey by Travelodge hotels is anything to go by, 72 say they don't go to sleep until they've checked their favourite celebs' tweets), with 18 of us also checking our mobiles for text messages before the light goes out.
Talking about text obsessives, 20 claiming to have been woken up in the middle of the night by their phone's text alert. And 51 of people claim they do their weekly online food shop before going to sleep, with one in ten even paying bills online while snuggling under the duvet.
