Last April I was diagnosed with a panic disorder after being hospitalized for chest pains, dizziness, tingling, etc. Since then I have been taking 50mg of zoloft per day and 2 mg of xanax. I have noticed if I don't take my xanax or am late taking it, I have diahrea, head aches in the lower back of my head, excessive belching, nausea, and coughing. Is there a possiblity I was missdiagnosed and have something much worse? Or are these just withdrawal symptoms. Thanks! :angel:
