I went to see the doctor today and talked about the headaches I've been having on and off, so he prescribed Naproxen, which is the prescription ingredient in Aleve. Apparently one of these pills can last most of the day. At this point, I'm game.
After taking one, however, I'm not doing too well. I'm not sure if this is because I hadn't had anything to eat, or something else, however, so I'll try again tomorrow after having something to eat and see how things go. I'm definitely wanting to get the headaches resolved, but not if it makes me feel worse.
