Should I be worried? I've been exhausted my whole life (lifelong insomniac) and I work full time as a teacher and am a single mum. So exhaustion is par for the course. But I've only started getting slurred speech in the last month or so. When I get a good night's sleep it does make it better. But it's back again by that evening/next day. I just can't face waiting for hours at the Dr for them to tell me to relax and sleep more (I would if I could...). But then there's a niggle that this might be a sing of something more serious....
