... have been having feeling awful since I have been taking this drug. I am alergic to most blood pressure meds. Bystolic is the only one that I have been able to take without breaking out in hives and my throat closing up. But I have noticed that since I have been taking it that I am losing my short-term memory pretty rapidly. I also have a hard time saying a word that describes an object. I feel like I am stroking out or something more and more now. I have talked with Dr. about this, but I have been so stressed most of my life that is probably why I am like this now. I really get scared lately. Has anyone else had this problem while on bystolic for this length of time?
