anxiety
"I used buspar 5mg once every few years.  It's very good for me and very mild.  I tried double dosage once and I was groggy.  But on 5mg, I was perfectly normal.  When I get my anxiety attack (once every decade or so) my hands shake, can't eat, color of my face goes pale....  but immediately soon after taking buspar, I feel much better.

Please note that these medication don't work just as well on everybody.  The nature of psychotropic medication would work wonders on one person, and horribly or not at all one another person.  You gotta keep trying until you find something that works for you."
