Joni,
It is hard to keep upbeat when your husband is having such a hard time right now. Like others, I have been up and down and the downs are really low when they strike. I often think it would be easier if it was me too, in that, it is much harder to see your loved one feeling so sick. My husband's fluid retention has not been as bad as your husband's but right now, he is in bed, and the fluid retention is making it difficult for him to move. He has gone through this before and for him, it usually means more bed rest and lots of gatorade. Please keep us posted on the results. I am here for you......
