Increasing sex drive depends a lot on why your sex drive is low. Considering your age I would first suspect estrogen dominance. As a women goes in to menopause their estrogen levels will drop some. Though their levels of progesterone drop drastically.
Progesterone is an estrogen precursor, though it is also an estrogen antagonist.
So progesterone regulates estrogen levels. Again as a women goes in to menopause their progesterone levels drop and estrogen is created from another precursor hormone. Though this leaves the estrogen unchecked due to the lack of progesterone. Other factors aggravate this as well such as estrogen replacement therapy, poor liver function, decreased levels of intestinal flora, constipation which allows for reabsorption of estrogen metabolites, diet, etc. The unchecked estrogen will cause lack of libido, weight gain, thyroid dysfunction, depression, etc.
