3 days a week I get up at 2am to start work at 3am and I usually go to sleep at about 10pm so by the time Saturday comes I am shattered being a lady of a certain age I should have more sleep really, Weekends I usually wake at 2am thinking I should be getting up then it takes me a couple of hours to nod off again. So my sleep pattern is rubbish really.  I get hot flushes, day and night so that doesn't help either, so I just tend to get sleep when I can and try not to worry about it which only makes it worse, a warm shower and hot chocolate usually works when I am not working.
