doobey - a woman?
First of all you need a medical diagnosis to eliminate serious pathology.
Then if it is peri-menopausal (and as I said in my earlier post, there is absolutely NO INDICATORS for this girls, take it from one who has been there!) you can then focus on finding something which mitigates the symptoms. Personally I don't think much of HRT and not many women know that it does not 'stop' the menopause or its symptoms but simply defers it so HRT users will get the full blast whenever they stop using the monkey-glands.
I would not - personally - experiment without expert guidance with anything which affects the kidneys. Artificial stimulation of the kidneys........for what? What will it lead to?
I picked up from your posts you were not a woman but you seemed to be reporting peri-menopausal symptoms. Would it not be more likely your girl-friend would be more content in her physical self if she engaged with these issues directly through discussion and support from other women? These are after all traditionally referred to as "womens' issues".
