Not been recovering for as long as you have but these long lasting symtoms are just plain nuts. After my accident for some unknown reason I didn't like the taste of milk. A bit bizarre I thought but hey I can live with that.

Recently to help my memory & planning ability I started cooking again. However, I didn't realise how much my taste had been affected until I made the most mild and tastless Chili - which is not what the wife said when she came down from the ceiling after trying it.
