I wondered the same thing then I started to think that maybe they figured that if they didn't tell you about it, maybe each person would perceive it to be different, i.e., not as bad as if it were expected, or maybe not even that noticeable at all. That doesn't sound right. I have a hard time expressing myself. Maybe they are hoping you will not experience that and are not sure so that if they don't say anything at all, you might not, whereas, if they even suggest it, you may experience it through suggestion. Did that make sense? I had problems with taste, they went away. I had dry eye but it got a bit better where I don't need drops but my eye doesn't tear. I did lose my hearing, no way around that! My throat was so sore from the tube in my throat for 11 hours, I wish it had been numb (well, just temporarily). My smell was okay, as far as I know. I was very lucky that I had no permanent facial paralysis! I am still alive, breathing, walking and talking!
