After 6 weeks of taking Buspar it appears all of a sudden I have side effects: heart pounding, lightheadedness, nausea. The doctor said it's not normal to have side effects 6 weeks after starting meds but took me off it anyway. I'm still feeling the side effects after not being on it for 2 days. Is this normal? If so, how long will it take for the Buspar to get out of my system?
