I've been on 50 mg of atenolol for 5 yrs. Currently weaning off, took 25 mg for 7 days and now am on 12.5 for the last 2 days. I'm going to try to skip my dose tonight. I have been having high anxiety and periods of high heart rate even at rest ranging between 90-116. BP has been getting a little elevated 140/86. From what I have read this is normal. But when will it all go away? I can't stand the feeling of my pounding heart!!!With activity I can get to the 120-130's. Please any info from past atenolol users needed. Thanks. Have already started taking dyazide but that has offered little help with BP seeing that it usually takes diaretics a few weeks to be theraputic. Right?
