Has anyone else been suffering from insomnia. I'm exhausted. I've been worn out and having to have naps for the last 5 weeks. (I'm 9+6). I went back to work last week (teacher) so have obviously been unable to have a little siesta. I've been ok with this and had been managing by going to bed by 9 every night. For the last three nights though I've woken at around 2am and been unable to get back to sleep. This then leaves me wiped out by 10am at work. Really hoping this doesn't last!!! Has anyone else been having similar problems?
