I am a nursing student and recently had two panic attacks within a week, and the last one was so debilitating that I couldn't eat, sleep or study. After 24 hours without relief I went to the doctor who prescribed zoloft 50 mg and xanax 0.5 mg PRN for anxiety. The zoloft has been making me shaky and nervous in the morning and I have to take one xanax in the morning and a half to a whole Xanax in the afternoon. I am worried about dependence because I find myself feeling I need Xanax at the slightest bit of anxiety. I know that it will take several weeks for the Zoloft to kick in, but I'm wondering if I will easily be able to wean off Xanax? I don't want to feel the need to take Xanax daily!
