I had to have a full hysterectomy before I was 30 so it came as a bit of a shock to experience the symptoms of early menopause. In fact I think many of the problems I now have sleeping stem back to this time. I had horrendous hot flushes, dizziness, often everything would ache so much that I felt battered & bruised, like I'd been in a fight or something. My mood swings were extreme (my better half said I was a massive nightmare!), it took about 2 or 3 years of trying different HRT to get anything that sort of helped (tried different pills, patches, think I even had some injections) - finally found one that seemed to suit me. Most symptoms eased but sleep remained problematic. I have very little energy but have complex health problems so it's hard to point to any one thing that is to blame for sleep problems - I think it is the combination of life, stress, illness, medication etc. On another note, in the last few years I've had similar but not as extreme symptoms, and have discussed with my GP if it's possible I could be experiencing something like menopause again now I'm nearer the age it would normally happen - unclear and due to lockdown not been chased up, yet.
