Niels: 11 months of an 'unguilty' supplement called Phenibut


Recommended Posts

Hi guys,


This is my first post, last year (2016) I took a supplement called phenibut from january until august 16. Now more than 11 months later I am still in withdrawal. I took phenibut for better sleep, but had enormous benefits during the day, I had no stress and felt like a god, so I took it daily and well above the recommended dosages, than when I quit CT not knowing hell was awaiting me.


Now I still have a lot of symptoms:

- dizziness

- fatigue

- balance problems

- legs feel weak and dizzy

- stiff neck on the backside, like there's a weight on it

- rapid heartrate when doing the minimal of activity

- exercise intolerance

- sometimes numb spots on face

- muscle spasms

- bloated belly


As far as I know nobody who took this supplement has suffered so intensly for so long?

It is shocking how something so seemingly innocent as a "natural" supplement can have such long lasting effects. Have you read our discussion on phenibut and other similar substances?

Kavinace, phenibut, or phenyl gaba for sleep.


You can find discussion topics about your symptoms

  • maybe in the links in this summary topic: Important topics about symptoms including sleep problems.

  • by searching the site using the site search tool; field is in the top right of every page
  • by using a web search engine with a keyword for your symptom, e.g. "numbness," plus site:survivingantidepressants.org as search terms.

That last bullet is a good way to find other discussions where phenibut has been mentioned in a post on the site.
