"i&#039;ve had a great experience with buspar 20 mg daily added on to 37.5 mg of effexor xr. i have genralized anxiety disorder and social phobia, and buspar has made an enormous improvement. the anxiety is not completely gone but much more manageable. buspar is a great alternative for people who do not want to risk becoming addicted to the narcotics, such as xanax. i take it twice a day in the morning and evening, 10mg each time. within the hour i feel less anxious and calmer. it takes a few weeks to fully take effect (about 5-6 weeks for me), which my psych told me beforehand and i found accurate, so give it time."
