Hello, I am 51 female and have been taking ToprolXL for 6 yrs. Started it for rapid heartbeat and added high bp the last 2 yrs. It has worked just finefor both probs.Unless I am upset. My hands and feet do stay COLD. I went to a diff doc--a reg MD. He wants me to stop the Toprol and take Zestril. I always thought you had to wean off Toprol. I am terrified of switching drugs. I also suffer from an inner ear dysfunction and have to be very careful about anything that causes dizziness. Any advice would be appreciated. I can't afford to see the cardio anymore. Am just very leary--this was my first visit to this new doc and he did not do any tests. I have read good things and awful things about zestril. HELP....Thanks, Belle
