Chances are, someone you know takes a sleeping pill. One in four Americans takes a sleep aid every year, according to the National Sleep Foundation, and the numbers are even higher for women -- one in three uses some sort of sleep medication a few times a week.
Why do women have such trouble sleeping? The reasons are as numerous as the passel of pills on the market: anxiety, depression, chronic illness, restless legs syndrome, sleep apnea, everyday exhaustion ... the list goes on and on. No wonder so many sleep aids are available.
