Bizarre is a good description (so is the butter)
I think your right on the law suit culture.
Its strange as there are risks to most drugs even ibuprofen
As discussed on other posts a lot of these non HRT self medication is totally uncontrolled in the same way true HRT is.
HRT is the same compounds as in the USA but with different brand names so no difference really.
In terms of the other serious items you see on their FB page:
"Firstly, the large number of women who believe they are going through peri in their 30's. Secondly, the number who are on numerous antidepressant/sedative medications, and thirdly the overwhelming consensus that hormone treatment is not worth the risks and to be avoided at all costs."
For peri symptoms for woman in their 30's, there is every chance of premature failure and possibly given their larger population your going to encounter more. There are so many factors to take into account but there could be a "me too" culture in terms of health issues there.
The AD and Sedative approach I find quite insidious. They are handed out like sweets from my own experience with little regard to the effects to those using them. I've experience within my family of being handed out these when the underlying cause was something really simple that a blood test would have picked up.
On the last item we do still see a lot of posts from people who's doctors are in that view and totally behind the curve on current information. Its a shame that there is not a standard or easy option people can take to alleviate this problem we all face from time to time.
