Its an antiepileptic/mood stabilizer often used for epilsepy, bipolar, and migraines. But its been shown to decrease glutamate whkch is the brains excitatory neurotransmitter. For me its allowed me to not only feel happier overall, but much more stable. *Not* flat or emotionless at all. Its almost like instead of panicing about my anxiety, im able to be like "well whatever thats there" and it goes away like 10 times faster. Also i deal with dpdr and thats gotten already like 50% better
