My late dh had congestive heart failure, also. The Dr. told him that he HAD to keep moving. As in walking. He didn't. I really don't know the answer to it, but keep doing what the Dr. says. dh was on some reeeaaaly heavy water pills. That only works so long. Water pills are hard on the kidneys. It is a "catch 22" thing. Water pills help get the water off, but the kidneys suffer. dh finally ended up on the dialysis thingy. If you are ok to sit in a chair & do NOTHING for 3 to 4 hours, It works. That was 3 days a week.
I am assuming that you are a diabetic.
They wanted to do a sleep apnea on him, but he opted out of that. Damn I really hated it when he seemed to know more than the Dr.
I wish you luck!!!!!!!!!!!!! And many prayers.
