Stopping Coreg To Relieve Fatigue?

I just posted something similar under an old question, so thought I would make it a separate expanded post.  I've been on coreg (50mg) since I was diagnosed with cardiomyopathy in 2006 (age 54).  I've seen doctors from UT Southwest to the Cleveland Clinic.  My ejection fraction has been measured from mid 20s to mid 40s.  The latest heart cath put it at 30%, the most recent echo put it at 36%.  The Cleveland Clinic cardiologist I saw last year explained to me that the ejection fraction numbers are all subjective and he noted some people with an EJ of 20% can be operating normally, while another person with an EJ of 40% can be virturally incapacitated.  

For me it's the fatigue I'm finding hard to live with.  Before my diagnosis I could work a full time job, teach a college course at night, do yard work and play in racquetball tournaments on the weekends.  Now, I'm lucky if I can log 3000 steps on level ground on my pedometer.  I've read that coreg causes severe fatigue.  I've experimented by cutting my dose in half (taking just 25mg at night before bed).  I'm not sure if it's the placebo effect or not, but I actually do feel a bit better the next day when I skip my coreg dosage in the morning.  I don't want to do my heart any long term damage, but I would love to get off some of these meds.  Is there a substitute for coreg without fatigue?  Anyone else have any feedback for me?  I want to put more "living" in my days.

Hi Ken,

Thank  you for the quick reply.  I copied it here just in case someone might be looking for it.

Yes, I take an ACE with the Coreg.  My resting pulse is low 60s, my regular BP  is low 90s over high 60s.  The doctors quickly got my Coreg dosage from 3.25mg BID to 25mg in about six weeks and I've been there for four years this coming September.  Recently I had a nuclear stress test.  I was off Coreg for 48 hours, on the treadmill I could only get my heart rate up to 130 or so.  Perhaps I'll divide the half dosage to twice a day to see how that works...thanks again for the post..John

I was taking Coreg CR (slow release) single dose of 25mg once a day. I went back to 12,5 mg twice a day,and that works for me. I take an ACE inhibitor twice a day with coreg just before a meal. That has been regimen for years...Why are you on such a high dosage?  

Do you function OK the next day when you take the dose at night?.  Is your heart rate normal...less than 100 at rest?  The doctor probably wants you take a dosage during the day when you are more active to help manage heart rate.
