At first I thought it wasn't working, because the info on it says it is supposed to make you very sleepy within 15 minutes. It doesn't make me sleepy at all, so I felt pretty disappointed, and my head was still racing, and I felt no different.

Then suddenly it was morning.

I don't take it every night. Last night I am quite sure I would not have slept without it, but I got through the night with only a few interuptions.

So it doesn't make me feel sleepy, it doesn't make me feel any different, but it definitley helps my sleep.
