I'll be truthful with ya, listen you your wife and Doc. I was/am hard headed, always been that way, took me three heart attacks, and I am still doing things my way but I seem to have changed on my own. Shame I didn't do that 15 years ago.
I don't remember getting any taste out of anything. Its like if it ain't salt, don't even wake the taste buds up. Check with the Doc, there is I am positive, a hospital nursing extention to help you with all these things. There has got to be something out there by now with taste without salt.
Last heart attack, you now have to eat something to get out the hospital, I had not eaten while in there. Pop brought strawberries everyday from the garden, like I was gonna eat that nasty hospital food. The midwatch nurse sneaked to the kitchen and brought me a turkey breast on sawdust bread w/ mustard. She watched me choke down 1/2 of it so I could get released the next day. See what those poor people had to put up with?
Again, have you tryed the Tony's salt free? Or is it more dried colored grass? Is cajun power salty? Probably it does have some taste to it.
Oh and that spray butter, "I can believe its not" does help cause it is an aromatic. The nose tricks your mind.
I do wish you luck man...... The alternative is worse than no salt and eating grass and cardboard.
