Knocks me out

9 people found the following review helpful

Posted by Reviewer1075233 on Jan 10, 2010

In terms of any kind of insomnia, one pill will knock me out quickly, surprising how fast. However the next day I feel very heavy, a little drowsy, and a bit foggy through the morning. I havn`t noticed any kind of `mood enhancing` effect, but the physical heaviness I get the next day prevents me from being in much of a good mood. I was interested in this primarily to aid with depression, but it makes me way too tired/heavy to be taken regularily and function mentally at 100%.

Good quality, but not for me

This product is a good choice, but having tried a number of different serotonin precursors including 5-HTP I recommend you to better try pharmaGABA and/or Taurine if your main problem is anxiety, because this can make you more depressed due to its dampening effects over noradrenaline.

I only used it once and found it ineffective so I didn't try it again.

Product works fast, but doesn't last all night. I get about 4 hours sleep, then am wide awake.
