"buspar has worked great on my mild to moderate anxiety. i take it in combination with ativan (as needed), but generally find i do not need the ativan more than a couple times a month. buspar has worked very well for me and has the great advantage of not being habit forming, so i feel safe taking it on the long term. 

that being said, it takes about 3 weeks to kick in fully. it also makes me dizzy if i take it differently than normal (with food as opposed to without, vice versa). it would also not be a good choice for someone with moderate to severe anxiety, as it is not a very strong drug. i take it in combination with a good diet and exercise, but doubt it would work as well without them."
