A slow taper off buspar was called for. Did you taper off it too rapidly? Did a mental health professional supervise & guide you while you tapered off buspar? Are these symptoms a return of your pretreatment symptoms? Does your treating physician know you're experiencing these current symptoms? If so he/she, who knows you best, will give you appropriate advice about treating them.
