Nigel,

I had lost my sense of smell over the years. Never thought much about it, but when I finally ramped up on my current Sinemet levels, it returned. Utterly amazing. Still very muted, but somethings I can pick up on.

I noticed also strong acids have a 'taste'. Lemon, tomato, onion, etc.... oh I love hot peppers, but much hotter than the rest of the family enjoys.
