high blood pressure
"I have been taking Toprol XL for 10 years. I began with 50 mg per day, and am now at 200 mg per day. Unlike another report posted here, I am sleeping better while taking the medication. The only two side effects I've experienced are shakiness and nervousness when I miss a dose by even a few hours and vague aural hallucinations (hearing things) while on the verge of falling asleep. I've seen the hallucinations reported by other toprol users on other sites."
