Here are some ideas from forum members that I posted in my journal:
My husband's specialty pharmacy also suggested red meat, marinated meat, and food at cooler temperatures.
I like the frozen fruit Popsicles for the metallic taste- strawberry is okay but love, love the lemon ones.
They help make drinking water a bit more palatable as well.
I have seen a number of sites suggest tart drink flavors will help. Here is one, has some additional ideas too. http://www.hepatitis.va.gov/patient/treat/side-effects-mouth-stomach-digestion.asp#S2X
I drank a zero water and it was enough for me usually.
Citrus or tart flavors help; I've also been a gummi bear addict lately; I've had the metallic taste for the past 5 months-ugh!
Biotine mouth wash for dry mouth seem to help me somewhat. I have had metallic taste all through tx and now at week 20 it's getting worse! Who would have guessed!
Biotine mouth wash is best I have found Sweets and sour stuff seem to make it worse . Use plastic forks and spons no metal forks or stainless steel.
Good luck hope it helps
