Good Sleep Aid

Posted by 4916842614598185317 on Oct 03, 2016

It doesn't help me fall asleep sooner (I use diphenhydramine HCL for that), but it improves the quality of my sleep noticeably.

After chronic sleep problems for 20 years, this finally got me to sleep. You need to take it immediately before you get into bed otherwise your brain will product chemicals to fight it if you carry on staying up. Turn the lights down low, swallow a pill, climb into bed and sweet dreams!!! I also had other issues aside from insomnia. In the end I resolved my issue by addressing over-stressed adrenals and took the herb Schizandra - miracle stuff. I am now cured of Chronic fatigue and Insomnia - and don't need the 5-HTP anymore. In my experience it is critical to get to the root cause of your symptoms in order to succeed in aiming for good health. It pays to see a Naturopath or Herbalist for some advice, although in this case I worked it out for myself, the slow and painful way - 9 years of searching lead me to Schizandra, a major Chinese herb with wonderful benefits.

Didn't work for me

Posted by 5136932930875589514 on Aug 14, 2014

my naturopath was reckoning this would be the cure all. I have had adrenal fatigue and some very weird neurological symptoms for a few years. of course depressed and exhausted. This product made me feel unwell in the stomach when I took it in the morning (supposed to take it on an empty stomach) and made me feel like I was being dragged under when I took it at night. Weird foggy feeling the next day. After much research I found out about Siberian Ginseng and Licorice (same brand) and the results after a week are much more impressive than the 5HTP. Keep trying till you find the thing that works for you - it can take a while.
