Mahea, a number of PALS have experienced similar things. I had a period of about six months where I could not stand the taste or odor of spices. Couldn't eat pizza, and felt I couldn't breathe in the presence of cinnamon, both of which normally I love. It happened very early in my speech problems, before I had any real swallowing issue, and then went away ... apparently for good.
I think moderator Al has experienced this, too, and he has limb onset like you. It seems to be one of those wacky
ALS symptoms that are so unlikely you start to think you're nuts.
