Metoprolol (Lopressor) question

For anybody on that med...I just went from taking Atenolol, 50 mg, 2 x a day for..oh geez 15 years at least, to taking the metoprolol. Same dosage..50 mg 2x. I was having LOTS of palps, and the dr felt that the Atenolol just wasnt working so much for me anymore. I started just this past Friday ( 07/24). I know the brochure I got with it, says it can take time to get into my system. But...one thing when I was on the Atenolol...my heartrate very very rarely EVER went out of the 60s. Even when I was active. Oh, sure, if I climbed stairs it would rise up, sometimes near 120 tops, but it fell right away too. I also never felt my heart beat, or pound a bit...EXCLUDING the times when I was having palpitations..of course I feel it then..but when Im just relaxing, I didnt feel it. ALSO...when on the Atenolol, i could even skip a dose..and my heartrate would stay down. Now..on this new med...gosh, if its even fairly close to the time that my next dose is due, and I, say, take a flight of stairs, or make a couple trips carrying heavy groceries, my heart is beating pretty fast. I timed it at 132 bpm, after I carried some groceries in ( its a rather long walk..heavy bags).

I dont LIKE this new med, I dont think!! I want my HR to always be nice and low like it was on the Atenl!! But then, maybe im not giving it a chance? Its only been 4 days that ive been on it.

I have a follow up appt with the Dr at the end of August..he wanted me to give this medicine about a month..then come and see him.

Anybody out there ever go from Atenolol, to Metoprolol..and actually LIKE it??  Ever have this sensation of knowing when its wearing off? I hate that.

I was on Metoprolol for about 2 years and had some weird experiences with it.  For several months, I was taking 50mg once daily.  I could not take more than that.  It seemed like every day, about 20 hrs after taking the dose, I would start getting a pattern of 3 normal beats, three hard beats, three normal beats, etc. for several hours until I took the next dose.  It meant taking a dose every 20 hours and that got really difficult.
I weaned myself from Metoprolol with my cardiologist OK and tried Atenolol.  I had some strange episodes when I first started taking it, but discovered that if I took only 12.5mg daily, it worked better than Metoprolol and was longer lasting by far.

I have been on atenolol for almost 5 years. I have tried other beta blockers including metoprolol. Metoprolol did not agree with me. It actually caused my heartbeat to race, or jump quickly, when I would get exerted. I went back to atenolol 25 mg.
