Changed to this product in an attempt to stop visits to the loo at night. I was taking "another" product for many months which had worked very well. The "visits" slowly got back to several so decided on a change. Have been taking Damiana for quite some time & find not only has the "sudden urge" of a loo visit during the day ceased but the nights are "Visit free" now, even with several glasses of water not long prior to bed. Great product.
