Indeed I am demo, it works great for me too, sometimes a little too much if I take it late. Upon waking up I sometimes feel very tired though. If I don't feel sleepy enough before bed I take it, but have recently switched to the melatonin sup (hey, sup!) because it doesn't quite cause me the same tired "hangover" in the morning. Of course, there are plenty of other tricks to try, such as drink tea and relaxing before bed. ZzZzZ
