I actually like Atenolol. I have been taking 25 mg a day for about 3 months now. I have take it at night as it makes me a bit drowsy, but by morning I feel totally normal. I have tachycardia and a racing heart. It helps my racing heart slow down a bit, but I still feel it racing, so will likely need to up the dose on my next cardiologist visit. So far, thumbs up for Atenolol.
