To @lesion I was very surprised to see that someone else has the voice changes. I have that problem as well. Mine tends to come and go and I haven’t found anything that fixes it. I have had success with the smell issue with the drug clorazepate. Although I was never given a firm diagnosis and my story is too long to type, I also think I had some sort of stroke about four years ago. The voice issue is so annoying. I’m sorry you have to deal with that.
