kicker, glad you reminded me about Amantadine's slight energy benefit -- I thought maybe I was nuts.
In Feb. a doc in TX at an urgent care facility and I disagreed about why another doc had originally Rxd Amantadine.
I tried to tell the TX doc that I thought it was to help with fatigue. He actually went to the trouble of printing out an info sheet about the drug to prove I was mistaken.

I've wondered about it ever since!
