@klp Hi Kelly and all. This new support group came just at the right time for me. In mid-August I had an emergency heart cath because of chest pain and a "wonky" EKG. It was determined that I did not need further treatment and went home. On day three following the cath I was having problems with my breathing. I have Mycobacterium Avium, colonized Pseudomonas, and bronchiectasis so I felt it had something to do with my lungs. We went to the ER and a CT showed Congestive Heart Failure, blood clots on both sides of the lungs. These conditions put me in ICU for six days and a telememtry room for one day. I was told I should make follow up appts with my primary, cardiologist and Nephrologist. I saw the discharge diagnoses #7. CKD, stage 2. What??? I had to look CKD up--didn't know that one. In the hospital discharge notes it said I am "chronically hyponatremic." Didn't know what that was either. OK, back to earth. They have me on UREA 15g twice a day. Does anyone understand about hyponatremic and this UREA product. The powder is awful. I've tried it in numerous liquids and it is still hard to take. I understand they have tablets and wonder if they are hard to swallow (too large). I see you have to take 8 tabs to equal one pouch of the powder. Any help or advice is appreciated. Thanks much. Faye
