Blocked ears symptoms and conditions

I am a 34-year old women who started 50 mg of Toprol-XL 4 days ago for a rash of panic attacks I experienced earlier this week, after having high blood pressure and occasional panic attacks in the last 3 months. Since then, I've had migranes for the past 2 days, bad allergies, stomach pain, loose bowel movements, slight difficulty breathing, frequent urination, and tiredness/lethargy during the day with trouble sleeping at night. I was already feeling strange my 2nd day on it and called my internal medicine doctor, who, of course, told me to stick with it. At this point, I'm ready for safer, natural alternatives. I'm will call the doctor tomorrow to tell him that my mind is made up and ask for instructions on how to wean off of it safely.
