Taken together, these preliminary findings suggest that dietetic approaches might be included as part of BD treatment. Also considering the high risk of metabolic disorders in individuals with BD, they should be encouraged to choose healthy dietary lifestyles, including daily intake of fruits, vegetables, seafood and whole grains.

Phenibut withdrawal appears to have a range of severity. It is important to recognize that patients undergoing phenibut abstinence may have progressive symptom worsening during early withdrawal. All published cases of abrupt phenibut abstinence were admitted inpatients for symptom management. Benzodiazepines or barbiturates with adjunctive baclofen appear to be the most commonly used drugs for moderate to severe withdrawal. Outpatient management via slow phenibut tapers with or without adjunctive gamma-aminobutyric acid agonist therapy may be successful. However, there is no standard treatment
