In almost all cases, the point of a program is to have effects other then mapping things going in to things coming out. The idea of controlling the side-effect is that you can organize code in a way that is easier to understand and reason about. If you put all the side effect together, in a place that is very explicit and central, it's easy to know where to look and trust that this is all that's happening, no more. If you have the input be very explicit too, it helps test the behavior for different input, and it's easier to use, since you don't need to change the input in a lot of different places, some which might not be obvious, just to get what you want.
Prescription naproxen comes as a regular tablet, an enteric coated tablet (delayed-release tablet), an extended-release (long-acting) tablet, and a suspension (liquid) to take by mouth. The extended-release tablets are usually taken once a day. The tablets, enteric coated tablets, and suspension are usually taken twice a day for arthritis. The tablets and suspension are usually taken every 8 hours for gout, and every 6 to 8 hours as needed for pain. If you are taking naproxen on a regular basis, you should take it at the same time(s) every day.
Various studies have found that MDMA use is associated with risky sexual behaviors. For example, both males and females who use MDMA are more likely than alcohol-drinking controls to engage in risky sexual behaviors (., without a condom). 85 MDMA use within the past 6 months is associated with initiating sex before age 14 and having two or more partners in the past 2 months. 86 In addition, people who use heavily report more sexual risk taking than those who use less often. People who use heavily are also more likely to have been tested for HIV, though they believe they are at low risk for contracting the disease. 87
