HRT following hysterectomy? Advice please!?

I am 7 weeks post-op following an abdominal hysterectomy. Ovaries were removed at the same time so I have been thrust straight into the menopause. Prior to that I had none of the typical menopausal symptoms for my age - 50! However, now I am suffering with unpleasant night sweats which disturb my sleep greatly, along with depression and short term memory loss. I have read all the pros and cons for taking HRT with all the risks involved but I have no experience of knowing anyone who has ever taken it. I'm keen to hear people's opinions - good or bad - thanks.
