... because of my anxiety so high. I know when it's going to happen so I take a Xanax & sit or lay very still & it passes. I didn't get my XR filled due to being afraid I may still get spells & have nothing to stop them. I refilled my xanax instead. Could someone please tell me their experience with the Xanax XR vs the Xanax? And, is it safe to take xanax & Xanax XR together?Thank you!
