Bless the internet, and bless this site! I have had HORRID panic attacks as I'm relaxing into sleep. While not glad about others misery with the same symptom, I am glad to find out it's most likely this medicine! I've been on Toprol for about nine months now. My Dr. started me off on 50MG, then we had to increase it to 100MG. I then started having extreme shortness of breath, and cut myself back down to 50MG. Mind you, my Dr. is not the one who realized it was the Toprol causing my S.O.B., but rather, I did! I recently had to increase the dosage back to 100MG ( with her approval) as my BP was creeping back up. I've taken up walking about 30, fast paced, minutes, if not daily, than at least five times a week. I've cut down to 1/2 pack of cigarettes a day ( I know, but what's an addict to do?) I'm trying to watch what I eat, and with the exercise I have now lost 13 pounds in a month and a half. =) Sadly, my headaches have returned, as have the ringing ears. I'm afraid it's time for a change in medication. Thanks for easing my mind about the nightly panic attacks!
