I too have suffered with night sweats and hot flashes, but not the nausea. To relieve the hot flashes, my doc told me to take 2-1000 mg. of Evening of Primrose capsules once in the morning and at night. You can find them at Walmart. They sure stopped the hotflashes and I also take an all natural plant hormone called "Estroven" 1 at bedtime, which is also available at Walmart. Hope this helps U!
