I am experiencing much the same kind of problems. My physician prescribed estrogen.
No matter what I said, she prescribed estrogen.
And I may need to take her up on that one yet ~ but I don't think estrogen is the answer, either.
What I tell myself is that the heat and the flashing are my body's way of dealing with whatever pre-cancerous cells there may be.
And I think that is true.
Estroven may help you. (Not estrogen ~ Estroven.) It has helped me, but not that much. Nothing helps that much.
Pamprin will help with fluid retention and mood swings.
Magnesium can be helpful for periodic restless leg syndrome (which usually accompanies my sleepless nights).
They say it gets worse before we finally enter menopause, and that the symptoms will be markedly decreased once we are no longer subject to such intense hormone swings.
They say we will end up in a good mood place, not a bad mood place.
Talcum powder may help you. Carrying soap and washcloth and lotion and deodorant may help.
If we acknowledge what is happening to us, we can deal with it as we choose to.
Either we are sweating (and sweaty) because we are going through menopause, or we are carrying our personal hygiene items with us because we are going through menopause.
It makes it more difficult when we think we are the only ones this is happening to.
You are not the only one.
Be as gentle with yourself and your body as you can, going through this.
In a way, what is happening to you now is a miracle, as you change from someone preparing, every month, to have a child, to someone preparing to reclaim her own body.
It is a miracle, really.
You will come through it.
