Are you lying awake at night, staring at the ceiling thinking about things that happened during the day, or things that have to be done tomorrow?

We've all had moments when anxiety and stress have interrupted our sleep, resulting in us feeling exhausted and irritable the next day.

But what can we do to stop it?

Sleep consultant, Tom Coleman joined Dermot and Dave to answer your questions on all things sleep.

As part of a weeklong, Mind Yourself Now special to mark World Mental Health day, Tom had advice on everything from waking up during the night to whether or not we should actually be napping.

Dermot and Dave will be joined by a number of experts to look at everything from dark evenings to social media, social anxiety and meditation.
