Just remembered, a few years ago I had trouble sleeping. My doctor told me to take 3 mg. of melatonin apx. 30 to 45 min. before bed. Melatonin is a natural substance made in your brain. I found it helped me. It is in the vitamin section in the drug store.

I googled it and found alot on it. Below is a small part ......

What is melatonin?
Melatonin is a hormone made by the pineal gland , a small gland in the brain. Melatonin helps control your sleep and wake cycles. Very small amounts of it are found in foods such as meats, grains, fruits, and vegetables. You can also buy it as a supplement.

What does natural melatonin do in the body?
Your body has its own internal clock that controls your natural cycle of sleeping and waking hours. In part, your body clock controls how much melatonin your body makes. Normally, melatonin levels begin to rise in the mid- to late evening, remain high for most of the night, and then drop in the early morning hours.

Light affects how much melatonin your body produces. During the shorter days of the winter months, your body may produce melatonin either earlier or later in the day than usual. This change can lead to symptoms of seasonal affective disorder (SAD), or winter depression.1
