Hi Brennie,
I don't remember having a salty taste other than when I would rinse and gargle with the baking soda and salt solution that I used during and after Radiation treatments. The solution that I used was 1 tablespoon of baking soda and 1 tablespoon of salt in 1 quart of room temp water. It would numb my mouth and helped heal the sores in there. I could drink water after gargling and some soft foods ( yogurt,etc )
Although I tried to eat, I used the PEG tube allot in the weeks you are at now. When I was able to eat, everything tasted either like cardboard or aluminum/ metal taste.
This taste lasted until about a month after Radiation for me, but I have heard others on this board state that they got their taste back quicker. As mentioned many times here, each person is different, so you have an estimate to go by.
My Best to everyone here
