Breaking these large molecules into smaller components involves: 1  movement: propels food through the digestive system. 2  secretion: release of digestive juices in response to a specific stimulus. 3  digestion: breakdown of food into molecular components small enough to cross the plasma membrane.
Over-the-counter pain relievers, like Advil (ibuprofen), Aleve (naproxen sodium) and Tylenol (acetaminophen), are presumed to be safe. Since they don't require a prescription, directions and warnings aren't always taken seriously.
You should not take Advil PM unless you can devote at least 8 hours to sleep. Common side effects include: constipation, diarrhea, dizziness, drowsiness, dry mouth, throat, and nose, excitability, gas, headache, heartburn, nausea, stomach pain or upset.
