Ooh, tigermoth, I hope so too, otherwise the batty old lady police will be round for me!
Jimmy and Copper, re the perimenopause, I had never heard of it until my cousin (same age as me) told me about it 2 or 3 years ago - I understood from her that although the actual menopause is supposed to last about 2 years, many women have menopausal symptoms over a much longer period (sorry!) than that. I think there are some comments about it on another thread here.
My main problem, pre-chemo, was terrible flooding every 26 days; using the absorbency rates printed on the Lil-lets leaflet I reckoned I was losing half a pint of blood each time - that stopped straight after the first dose of chemo so it wasn't all bad! (Hair now more or less back to normal though but the new regrowth period was interesting as a lot of it came out vertical - sticking up through old hair - also with kinks in different directions - had it cut really short eventually but I looked very odd for a while!)
I wasn't getting hot flushes then but have them now - I can't have HRT because my tumours (breast cancer) were hormone-receptor-negative, I don't understand why that means I can't have oestrogen (sp?) but it does. However my GP said I could have progesterone tablets instead (don't understand why that is OK either!) and they do work, but every time I finish a packet I wait to renew the prescription to see how badly they come back - after a month or so they are building up again a bit. Mine are mostly at night, not sweaty, just HOT - prickles all over - spend the night waking up hot, tossing bedclothes off, then waking up cold and yanking them back again; I wonder if this routine accounts as much as anything else for the forgetfulness, mood swings etc!
Haven't even thought about alternative remedies so no idea about black cohosh (sounds like a renegade Cherokee)
