Do you have trouble falling asleep? And have you taken every kind of medication? Well, try melatonin. It is a natural medication used for the aid of sleep. What differentiates it from the others is that it is natural. It is an amino acid, even found in foods like turkey and cheese. It works on the peneal gland in your brain to help regulate the "body clock" and helps you fall asleep. This medication works great if you have insomnia, you do a lot of night at work or you just don't get much time in the light. You know when we eat a turkey dinner, or if you are out all day in the sun, generally you're tired afterwards right? Well this will make you sleepy half an hour to an hour after a 3mg dose. Studies show that it has helped regulate the body clock in your system. Look for it at your pharmacy and ask them more about it. I've been taking these for a while now.
