I think I'm doing well if I get 5 hours sleep in night - if I'm lucky I get 6 hours but many nights I will get less than 4 hours and every night I have 2-3 trips to the loo. I do spend 8-8.5 hours per night actually in bed but my sleep is better when I've done lots of exercise during the day.
Are you saying that your sleep problems began after your started the HRT or is it just the last few nights? I would suspect it is not menopausal or the HRT itself causing the problem but something else causing the night flushes. You may have a nasty virus - so perhaps you are running a temperature and don't realise it? There are low grade viruses that make us feel really unwell and simply give night sweats and extreme fatigue. It is so easy to simply blame the menopause of HRT for every symptom we experience.
As you are very post meno, so started from a very low hormone base line, it will take much longer for your body to adjust. I'm afraid HRT doesn't suit everyone and may not give you what you are trying to achieve.
As I so often say, it takes a whole range of strategies to adjust to this next stage in our lives, HRT won't fix everything - we are never going to go back to being 30-40 or even 50 again - we have to find a new normal that we can live with.
We have to pace ourselves, build plenty of exercise into our day with proper relaxation in between. Eat as healthily as possible but only small amounts regularly throughout the day.
If you feel so dreadfully ill, then you need more advice from your doctor about how you can tackle this. DG x
