My past psychiatrist said I should take it "as needed".  However people/articles say it takes 3-4 weeks to get the full effect. Both of these are contradictory, and seeing as how Buspirone has a half life of only 2-3 hours the latter doesn't make a lot of sense.  Otherwise why would you need to take it 3 times a day? Can anyone share their experience with Buspirone or maybe clarify what's correct here?
