Phenibut

If you are into Nootropics which are a sort of legal substitute to illegal drugs

Nootropics definition:
"Nootropics (/noʊ.əˈtrɒpɪks/ noh-ə-TROP-iks) (colloquial: smart drugs and cognitive enhancers) are drugs, supplements, and other substances that may improve cognitive function, particularly executive functions, memory, creativity, or motivation, in healthy individuals."

Phenibut definition:
Phenibut is a chemical similar to a brain chemical called gamma-aminobutyric acid (GABA). It is used as medicine. Phenibut is used for anxiety, fear, trouble sleeping (insomnia), tension, stress, fatigue, post-traumatic stress disorder (PTSD), depression, alcoholism, and irregular heartbeat.

The best use that I found for Phenibut is for sleep disorders and social anxiety and depression. There really is anything like this. If you take the right recommended dose of 250 mg for a 24 hour period it can really help you with those problems without any side effects. The trick is to drink coffee after taking it to balance the tiredness that the this drug can cause .

The best thing I can recommend is taking a 250ml dosage before sleep and the morning after will be a very peaceful one with no stress and anxiety and this will cancel the tiredness.

This is not a health advice just my experience with this Nootropics. Check with your doctor if this is allowed for you.
