Atrial Fibrillation
"Coming up on 1 year of Tambocor   Metoprolol for treatment of atrial fibrillation. It works very well, no attacks at all since starting Tambocor, hence my life is better in that respect. However, there is a trade off, my energy level is lower and I feel exactly the same when I get up at 7:30 in the morning; whether I go to bed at 9:00PM or stay up until after midnight. I am chronically tired. Also, I notice strange things with my peripheral vision occasionally since on the Tambocor. That&#039;s not to scare anyone off, I can still function normally, from yard work, to splitting wood, to playing golf, on the outside I doubt anyone who knows me has a clue that I am on medication. It is a &quot;feeling&quot; to me. I can tell I am a little &quot;off&quot; but it&#039;s worth it."
