I m taking 150mgd Atenolol, Adalat LA 30 x3 daily., plus other meds for Diabetes Type 2 Insulin etc. I have breathless episodes with only mild exertion, or, when I sleep, sitting vertical, or pillow at 45 deg. My heart rate is slow, a bit irregular, and when I sleep gets even slower, I use Pradaxa 150mg. Also have fluid retention mainly in legs and feet, compression stockings, Farrow wraps don t stop the leaks. This plus a whole theme park of common and not so common side effects! My main concern is resolving the slow heart rate and breathlessness so I can move faster than a sloth!
