Oh yeah, sounds great

What the hell is it?
Beta-phenyl-gamma-aminobutyric acid, better known as Phenibut or less commonly Fenibut or Phenybut, is a neuropsychotropic drug, derived from the neurotransmitter GABA that is capable of passing the blood-brain barrier. Phenibut is cited as a nootropic for its ability to improve neurological functions. It was discovered in Russia in the 1960's, and has since been used there to treat a wide range of ailments including anxiety and insomnia.
The name Phenibut, along with many of the other names for the compound, comes directly from the chemical name for the compound, beta-phenyl-gamma-aminobutyric acid.
Structurally, phenibut is similar to baclofen and phenethylamine, although it is not considered a phenethylamine. Phenibut is a GABAB receptor agonist, with slight activity at GABAA receptors. The pharmacological effects of phenibut are virtually identical to baclofen.
Phenibut should be used with extreme caution as it can have unpleasant withdrawal symptoms. Side effects can include acute anxiety and insomnia that can last for up to two weeks afterwards. Withdrawal symptoms, however, are almost always associated with cessation after prolonged usage. Tolerance to phenibut can develop quite rapidly.
Phenibut should never be mixed with alcohol, sedatives or prescription medication without consulting with a healthcare professional.
Persons on MAO inhibitors or epilepsy medications like carbamazepine or oxcarbazepine should consult with their psychiatrist/physician prior to supplementation with phenibut. Clinical research has demonstrated that phenibut can potentate or inhibit the function of some epilepsy medications.
