I have been taking Atenolol since 2001. I take 75Mg each AM and am taking it for occasional Atrial Fib (AF) episodes. I have not had any physical impairment, or problems with being tired or problems things mentioned here. All in all, I have tolerated the Atenolol well. However, recently tried taking Lisinopril (only 4 days and I hate it and have all the problems you mention here and more) as it is suppose to help reduce AF. HOWEVER, I have seen several significant metabolic side effects since I started taking the Atenolol I wanted to share. 1) I gained at least 20 LBS in the first year. 2) I became insulin resistant and saw my Triglycirides increase significantly (from the 200s to the 700s) and I have had to reduce carbs to keep them low, 3) I have seen my blood glucose (BG) levels rise resulting from the Atenolol. I have experimented and found my fasting BG levels in the AM are around 105 BEFORE taking the Atenolol, then within a hour of taking the Atenolol, they go up to 150-160 - that is without eating anything. Be aware of these implications. I am trying to find something as an alternative to Atenolol due to the BG levels, but have not yet. As I said, I tried Lisinopril, but that won't work.
