CBC hun, you tried adding plenty soya to your diet? and wild yam (Dioscorea I think the genus is called, might be Discorea, there are other wild yams used as food amongst other things, but thats the family thats useful for pre/post-menstrual symptoms, these are mostly caused by the drop in oestrogen levels) is available as a supplement, health food type sources. Both contain phytoestrogens and should help your hot flashes my dear.*squeezes CBC* Tofu for instance.
Its searing hot here,
