Query: Works well for moderate sleeplessness!

I was told to start small with melatonin doses, so I chose 5mg. My restless nights are pretty awful, so I didn't expect to get much of a result. First night I took these, I felt naturally sleepy for the first time in a good while. I was out in about 10 minutes. Doesn't leave you drowsy either. 5mg won't work for everyone, though. If you have more severe insomnia, I'd reccommend a higher dose.
