I have thyroid related AF but now my heart is in sinus rhythm and has been for quite some time. I take 3.75 Bisoprolol and 2.5 Ramipril per day but feel after 12 months this is too much. I feel weary, dizzy and quite blunted and really can't be bothered with anything. I also take 10 mg Carbimazole per day and 8mg Warfarin. I feel I am now overmedicated. Any thoughts?
