@gloaming. I Just weaned off Metoprolol and feel quite a bit better. Don't feel so washed out since quitting. I'm still on Amlodipine and Losartan but my BP is still holding below 120/80 with a resting PR of 65-70. I've been on this metoprolol beta-blocker for years and am not sure I ever did need it. I started taking magnesium glycinate about 5-6 months ago and my heart palpitations have diminished considerably.
