I currently take Coreg 40mg in the morning along with my other meds of Vyvanse, Lexapro and Klonopin. I'm not experiencing as much of a low energy fatigue feeling since I switched from metoprolol to Coreg so I started taking that during the day. With Coreg being controlled release is it still going to be as effective if I take it before I go to bed at night rather than after I get up in the morning? Can anyone share good or bad experiences by taking a beta blocker in the morning or at night?
