My BUN and creatinine levels are high once again. I drink as much water as I can. I am constantly drinking water. I get tired of it sometimes so I will add some powders or fruit to have it taste different however my levels are still low since I am on high doses of steroids due to an acute case of rejection. So I started juicing again. I made a pear juice this morning and I am about to make an apple celery juice. So if you cannot drink any more water just add a fruit, water and ice to your blender and drink away. The fiber is good for you too!
