not sleeping well lately

[Andy69]

I don't think it's nerves. I've had times when I couldn't sleep due to nerves and this is definitely not the same thing. It's not that I wake up and start to worry, just that as soon as I wake up in the middle of the night, my brain switches on and I'm fully alert and ready to go. Yet, I'm still tired because, well, it's the middle of the night and I've only had a few hours rest.
