Often I need to capture some thoughts whilst in bed - but I am often too tired to get out of bed to write them down. So I am brainstorming the best way to capture these.

I am thinking a small white board would be good as it is very easy to write and that's good when your half asleep. Perhaps a very small white board that can be grabbed from under the bed would be a good idea - not sure if would be good in the dark.

Anyone got any tips for this situation?
