I recently started taking Melatonin. I started taking this because everything else knocks me out. Melatonin is a natural sleep aid because it is one your body makes. Some depression meds can cause a decrease in the production of melatonin in a persons body. I curently take 300mcg which is just less than 1/2mg. It comes in a variety of "strengths" and is an over the counter, but recomends asking dr before use. It works in about 30minutes. I have never woke up groggy and didn't have to have that 8-10 that most Rx drugs need. In fact one night i got like 6 or 7 hrs of sleep and I was still ok. I wasn't dragging.

The site below is a great site for information.
