Well, here I am again. Been awake since 4 (again). Too exhausted to get up. Can't quite get back off to sleep. So what I do in this time (every morning at the moment). I play word-feud which is a scrabble like phone app. It's international so there are always other players online. And you chat to your opponent while you play. It keeps me fairly sane. And I can doze on and off between turns. I usually have quite a few games going, and they can take several days to finish sometimes, if people take a long time to make their move.
i thought I'd share with you what I do instead of sleeping. But I'm also interested to find out What you do? Always looking for new ideas.
