What did you decide. Did you stop? I looked several places, although I did not see any direct link in the few places I looked, I did see that potassium levels can be affected, causing reduced levels. Many organge juice brands list potassium, potatoes, bananas, all decent sources of dietary potassium. Ask your pharmacist as well about the palpitations and prednisone, he or she may be able to help.
