I was on 25 mg extended release for rapid heart rate and anxiety. They switched me to regular 25mg twice a day. I have achy kidneys, peeing constantly. Exhausted. Back hurts. Heart beating out of control. My BP is fine, my HR Is 120-150. Can't sleep. Hair is falling out. Gained 10 lbs. I am a mess. I am 5'8 160. A female. 56 years old. Feel like crap all time. Can't function. Some one else please tell me it's not in my head. I already suffered from anxiety, but it is over the top and, this is adding too... UGH! I struggle every day to get out of bed & go to work. Help!
