Atenolol
"I was prescribed atenolol for hypertension and high heart rate (12 mg, once daily), unless my heart rate gets down to 60 or below. It seems great, in that I am "calmer" or more relaxed; but the only thing I am wondering about is the slow weight gain. My diet is the same now as it was before when I started taking it. I am calling the physician to see if that may be why."
