I've been taking Xanax for about 4 years now because I have panic attacks but every time I get a new job the doctors or nurses or whoever at my drug screening tell me how bad it is that I take anxiety medication and that I can't work there unless I take a small dose 12 or more hours before work. I don't even work with heavy machinery. That and now that I have seizures I'm never going to tell them about the medication I take for that. The conversations with them are flat out intrusive.
