Not sure what brand it currently being used by my pharmacy but the exhaustion you talk about is all too familiar. My pharmacy has a bad habit of generic shopping and I find the size/shape/color of most of my generics changing with each three month refill as they change from one manufacturer to another to another.
Polygamy: is a condition or practice or culture of having more than one spouse at the same time. It is also known as polygyny, polyandry or plural marriage. Polygamous nation: a country where polygamy is a legal culture (i.e. Nigeria, and most countries in Africa, Middle east, nay, most countries in the third world).
Forms of hypergamy have been practiced throughout history, including in India, imperial China, ancient Greece, the Ottoman Empire, feudal Europe, and the United States. Today most people marry their approximate social equals, and in much of the world hypergamy is in slow decline: for example, it is becoming less common for women to marry older men.
