I Am 66 Years Old And Have Been On Prmarin

I am 66 years old and have been on Prmarin since I was 37 following a total hysterectomy (ovaries too). My natural e will no longer cover paying do it at my age. I weaned off of it by gradually going to lower doses, the cutting the lowest dosage in half, then every other day and have been totally off for three weeks. The hot flashes and night sweats and irritability are almost unbearable. I am desperate for some relief. I started Black Cohas two days ago, but so far nothing. Rapid weight gain too because craving carbs. Do you have any advice?
