Xanax. trying to get off of it. can literally make you sick. Sick enough for laying on the couch for a few days. Make sure you gradually stop taking the Xanax and see your doctor. Just being on Xanax for a month can give a person problems getting off of it. You can become dependent on Xanax one month after starting on Xanax, and you might not notice until you attempt to get off the drug.
