Not too impressed

I am sure this is a high quality form of Tryptophan based on the brand. However, I ordered it because of all the promise Tryptophan supposedly holds as being very helpful for insomnia. This did not help me with my lack of sleep, and when I pop one at any time of the day, (empty stomach)I really can't tell that I have taken anything period. On the other hand, 5-htp sends me into another world but also does not help my sleep. These supplements are tricky, I think that in most instances you are better off taking Rx as you can at least count on a degree of consistentcy in how they actually perform.
