I'm 45, and the proverbial hit the fan late last year. I actually ended up in a&e for 7 hours, on a drip and a heart monitor, because I felt so horrendous just before Christmas.
My GP, the a&e doctors, my friends all look at me like I'm mad when I mention perimenopause - "you're too young!", so I'm off to see a private women's health specialist (she's reputedly a life saver and all-around guru!) tomorrow...another reason this site is so fabulous!
