John, GNC used to carry liquid melatonin. But I believe they have stopped making it, because I can't seem to find it anywhere. So I started getting Melatonin Liquid at my local natural market by Natrol, Inc. You can go to: http://www.natrol.com/products/index.htm and search for "melatonin" (the liquid is SKU# 457) and at the top of the page there is a "where to buy" link. Enter your zip code and it will tell you where you can purchase it. I hope this helps! Leslie [Posted in FML issue 5173]
