I have been experiencing anxiety that would cause insomnia. My doctor prescribed 10mg Buspar twice a day. I took one dose on Wednesday night and threw up that night. I thought maybe it would get better if I split the dose to 5mg in morning and night yesterday. I have been nauseous every since (my last dose was yesterday at 4pm). It has been over 24 hours - when will this nausea go away from the medicine now that I have discontinued it?
