I'm so sorry to hear the symptoms are getting worse, Tanya. I really wish I lived nearby so I could at least give you some company, help with chores, whatever. I guess the best thing at this point is to take it one day at a time, try to get lots of rest, and focus on recovery.
About the taste thing, I've had two different conditions (Bell's Palsy and pine mouth) that have screwed up my sense of taste for a couple of weeks at a time. The Bell's made everything taste really terrible, and pine mouth made everything I ate taste super bitter. In both cases, the only food that tasted somewhat OK was plain white rice with nothing on it (basically, sweet and salty both tasted awful, but for some reason plain rice, which is normally kind of bland, was the only thing that still tasted like it should). So maybe try that?
