Atenolol and heart attack

I have been taking Atenolol 25mg./day for 5 1/2 months for high blood
pressure. I am a 63 year old female. The side effects for me are
tingling in my fingers, which is especially annoying at night, and
muscle pain in my legs. I did not associate either of these effects
with the drug until I researched it on the internet and learned that
they might be associated with atenolol. I have since reduced the
dose in half and am experiencing less tingling and muscle pain

I am trying to wean off of Atenolol bc it makes me tired and I feel as though my metabolism has slowed down. I have been on it for one year due to a fast heart beat. I did not have hbp when prescribed and I don't now. I was suffering from anxiety due to katrina and quit smoking. sometimes I feel sick to my stomach. has anyone gotten sick to their stomach from this med. also, I found that if I take it at night I am not tired during the day but I do have strange dreams.
my real question is how can I wean myself off this drug. I am afraid that if I stop it I will be somewhere and my heart will jump out of my chest.

I've been taking atenolol 6 months now and my basic complaint is the coughing. I have to practically sit up in bed at night. At first I thought it was just the usual summertimer postnasal drip causing the cough so I put up with it. Have to take ricoloas or some kind of drops all day to keep the cough down. I've heard other pills like this all come with the cough. If there is another that DOESN'T maybe someone can get back to me a nd let me know.

I have a doctor who isn't very communicative but if I complain about something he does what he can to try something else. This time, however, I'm doing my own research and so far have come up with zip as to any replacement. In fact, my blood pressure isn't much better. Was in the office for another reason the other day and it read 138/100.

Thanks!

Have been on Atenolol for about one year. Cannot function due to shortness of breath, very tired and sometimes very weak. Have muscle pain associated with this as well. Had a heart attack and that is why I was put on Atenolol. Never had high blood pressure before, but now with Atenolol find I cannot function. Hoping to get one something else with l ess side effects.
