    I'm a chronic insomniac and I started taking 2g an hour before bed, on an empty stomach, a week ago. Already, I'm sleeping better and I am no longer struggling through the days, yawning continuously. (my sleep hasn't been perfect, hence the 4 star rating, but maybe I haven't been taking it long enough) Powder is difficult to mix, however it doesn't taste too bad.

    See no advantage over straight Melatonin

    Posted by LanceSavoy on Sep 16, 2010

    Did not think it worked as well as Melatonin for getting to sleep. Also it really does not mix well with either water or juice.

    I have used Tryptophan for the past few weeks and think it has helped my sleep patterns/mind but also to assist in digestion as well. Overall not a bad product

    I used this several times over the past couple of weeks it seems to calm me down more than make me sleepy.

    Seems to help me sleep. It doesn't dissolve as well as I would like in water. I will try it in a warm liquid in hopes that will work better.
