so i went to the dr today for a follow up from my chest xray and EKG..she said all looked good..we talked about my increased health anxiety since my brain surgery and how my heart palpitations have gotten worse (i have always had a fast heart rate) so she decided to start me on metoprolol ER 25mg one time a day...she wants me to take it before bed because i told her that when i wake up in the morning i already feel like i drank a pot of coffee (and i don't even drink coffee because i can't stand the effects of caffiene) she said it should help with that feeling..so my health anxiety is making me dread taking the pill because i'm worried it will slow my heart down too much and i won't wake up in the morning..uugghhhh
