Valerian root or Valerian root -w- hops in either tablet or tincture form, Jan de Vries sleep easy blend, or Bach Rescue sleep are all available from your local health food store. They’ve all worked well for me in the past.

Some things and methods are better than taking medicines to induce sleep. Go for a walk, play games, and exercise so that you get exhausted and have a good sleep. Besides allowing you to sleep, these physical activities will enhance your health, your speed and agility.

I am a big fan of Melatonin. It gently helps you establish good sleeping patterns. I used it when I worked 3rd shift.
I’d do a little research, some people don’t like it, but it worked without any side affects for me.

The best medication over the counter sleep medication is Unisom. However, all medicated over the counter sleep medications carry loads of side effects. The best non medicated over the counter sleep medication is Nature Made Sleep, hands down it works better than other sleeping products, including those with medications in them and prescription sleep aids. Nature Made Sleep contains Melatonin which the body needs to get a good night’s sleep, along with L Theanine (the ingredient in turkey that makes you tired after Thanksgiving dinner), and other all natural ingredients that will help you get a good night’s sleep. It’s also the only over the counter sleep medication that is drug free, all natural, and non habit forming.
