Not a bad choice. Buspar is relatively well-tolerated IMO compared to a lot of other medicines (in terms of gene expression changes, drug interactions, incidence of life-threatening reactions, and long-term influence on brain chemistry), but if it's making you dizzy and giving you brain fog, it might be best to lower your dose or quit entirely.
CBD is difficult to attain in Finland, but there is ample promising research into its benefits on anxiety. It works by the exact mechanism as Buspar (5-HT1A agonism), and it potentially has a few others, too (GABAergic regulation[1][2] and mild FAAH modulation[3]); similar to Kava, it has mild persistent or long-term benefits even after the medication has worn off. It is generally well-tolerated and has substantially fewer side effects or risks compared to most anxiety medicines available on the pharmaceutical market. CBD also has zero addiction potential or dependency liability; rodents do not self-administer it in an addiction model, and it does not substitute for any drug of abuse in a drug discrimination study. It does not affect cognition, cause brain fog, impact one's mood, or have any withdrawal effects.
Therapy, meditation, reading, self-acceptance, exposure, and abstaining from substance use can also help reduce anxiety. Kava and Magnesium have a growing body of research in the treatment of anxiety.
