Hey Ron, my girl went thru the same a little while back. The zoloft didn't give her the random fevers and insomnia but did give her the constant dizzyness and lightheadness. She too was prescribed Xanax and even at a low dose became addicted quickly. All of these medications though depend solely on the user, some react diffently. Your right to feel weary of the Xanax though, it has a very high dependancy rate. As my girls caretaker I asked her doctors if she could take the citalprolam just before bed, as it does usually take 6-8 hrs to get into the system everyday and they said it was ok for her. Worth asking anyway! She now takes topomax and it seems to do alot better for her. I wish you luck sir, and I hope everything turns out ok.
