LiveScience.com - Brian Brown has been taking antiretroviral drugs for five years. If he stops, the human immunodeficiency virus, or HIV, in his body will multiply and eventually, he'll get really sick. "You have to take them with food," Brown said. "Even if you aren't really hungry." A 39-year-old licensed practical nurse, Brown has to remember to take his drugs daily. It's a routine familiar to people with all kinds of chronic diseases, including HIV and diabetes.
