Have been off buspar for 14 days i was just wondering why some withdrawal symptoms happen at night around 6pm? they are mostly dizziness ,head pressure, weird brain feeling? no other health issues, already been checked by primary doc?

Dizziness, weakness and changes in blood pressure can occur during Buspar withdrawal. If you are noticing them more around 6pm, this would coincide with a natural fatigue-related end of the day dip in hydration, blood pressure and other normal functions. Try to rest during this time period and focus on increased hydration especially with electrolytes. The symptoms will lessen over time.
