We have all experienced one of those nights when we just tossed and turned without sleeping well. Possible reasons could be we couldn’t turn off the thoughts running through our heads, maybe we were anxious or excited about something that was going to happen the next day, or we’d had too much caffeine before going to bed. Maybe you are one of the lucky ones who has had only one or two incidents of sleeplessness among many good nights of rest. However, for millions of Americans, those nights of restlessness and sleeplessness are a repeat occurrence. When not being able to sleep becomes so common that it begins to interfere with your daily routine, you could be suffering from insomnia. Unfortunately, many people do not realize that insomnia can cause some serious, even dangerous side effects.
