According to the makers of Tylenol PM and Simply Sleep medicines, some 65 million Americans have trouble getting a good night’s sleep. So besides pushing its products as one way to achieve steady Zzzzz’s, parent company McNeil-PPC has now launched iSlumber.com, a site designed to identify sleep disorders and offer some remedies to get the sleep your body needs. That’s all well and good, but the site switches soooo slowwwwwly between screens, it’s enough right there to make you nod off. We also have a sleep suggestion based on a not-so-scientific method we uncovered: Stop taking pills, push yourself away from the Internet, lace up a pair of sneakers and go for a 40-minute walk. We’ve found if our body is naturally tired from physical exertion, it will sleep on its own. And it doesn’t cost anything.
