Try the Salagen. I need to remember to take it enough. My RO said up to 4x day is normal.

My taste is about 75% of the way back. Chocolate tastes better, but not the same as before, and overall just a little diminished taste.

I never had a big problem with fatigue. I continued working through treatment, except for 3 days in the hospital for the neck dissection. Now that is not a recommendation to anyone, just the way it was. I tend to overdo in the other direction. ;-)
