Thankyou for all your comments and links. I am 56 and had an hysterectomy (ovaries spared) in 2002. Had a quick read, and looks like I need to stay off the black cohosh. I also have a thyroid problem with some other autoimmune conditions, and I am having trouble increasing the dose of thyroxine. All very confusing, have had chronic anxiety symptoms for last 10 years, which is why they put me on benzos. I think though, this has been a mixture of poorly diagnosed thyroid and the onset of menopause. Will keep reading your very good site.
