"i have been taking buspar for just over 8 months and i take 60-75 mg a day, depending on the day. i take for panic attacks associated with ptsd. i have had no side effects from this, but i do know when i have missed a dose, so when i do come off this i do expect a withdrawal period but for now it has helped me regain a normal life. i take this with a few other medicines such as celexa, wellbutrin, trazadone and seroqeul. this really works."
