Being woken at night by what I can only describe as trembling insides,not limbs as such but everywhere else.I immediately started to worry about this being symptom for MS or Parkinsons however have just googled and menopause seemed to be a possible cause.Has anyone else experienced this? I turned 46 this week.My periods are regular,although now only 24 days apart and I think I can only remember ovulating once in the last year.I'm extremely tired all the time and PMT is getting worse and lasting longer.I think my mum was about this age.Would appreciate any words of wisdom.
