I'm so sorry to hear about this. When the doc calls with the results, make sure to mention this.

When my tongue is very numb, my sense of taste goes out the window. I rely a lot on my sense of smell for cooking at those times, otherwise I really over spice stuff. Great for me to make the taste stronger, not so great for hubby.

I also have to be very careful when it comes to hot food and drink. I've managed to burn my mouth a few times.

I will agree it can get annoying when stuff doesn't taste like it should and can be disconcerting. Hope this clears up for you soon.
