I can't remember the last time I slept all night. My sleeping improved once I took up running but even though I run most days it makes no difference now. I also have a walk if at least an hour every day, sometimes twice a day. I'm so exhausted today and while I don't care how I look it makes me sad I'm so tired it is obvious. Has anyone got any ideas for anything I can take to knock me out so I can sleep? Three weeks I nodded off at the wheel of the car and it had terrified me. We were so lucky as it was a very busy motorway. I'm waking twice a night for the loo and struggling to sleep again as well.
