A Wonderful Supplement for Sleep

Posted by Reviewer2588465 on Mar 28, 2013

I've found that Tryptophan and Magnesium are what I've needed for a good nights sleep. I stopped waking up several times a night when I started taking these. I don't know if I'll ever stop waking up in the middle of the night completely, but these sure have helped. Try this free sample and give it a shot.

Did not notice any effect, while from L-Tyrosine I do notice a really good and lasting effect. I would need to try this more carefully to know.
