To Tired To Sleep

When watching TV we often see tons of commercials displaying the sleep deprived population. Drug companies love to sell the quick fix. In psychology it is often noted that all people need to do to sleep is change behavior, like not watching tv while trying to sleep. Advertising, specifically drug companies, have us convinced they have the answer. Some people may need drugs to aid them to sleep, but how did we become a nation of insomniacs right around the time these drugs came out. Odd?
