Hello
PrimeTimer and thanks for the update.
I am so glad for you both that your husband's potassium has come down to 5.4 !!!
Good luck tomorrow at the grocery shopping ...
... I have noticed that my potassium-readings have become much better
since I have started to cook all vegetables in lots (I really mean lots) of water,
because the water "washes out" lots of potassium.
It also helps to change the cooking water a few times ...
This may sound like lots of work but after a little while it all becomes routine...
Good luck to you both from Kristina.
