"i take between 30-50 mg per day depending on how i feel. usually 15mg or 20mg at a time. doctors should really look at this medicine for bipolar as i am severely bipolar (with anxiety) and do not like addictive substances. buspar is a wonder medicine for some! i&#039;m getting my life back! i no longer rage and ruminate, and i can also sleep, and think more clearly :d most things do not work for me but this one did."
