Here's my problem.  My daughter has the flu and my wife is coming down with a 
cold.

Neither one will drink the CS because they have drunk it before and hate the 
metallic taste.  i really don't notice much taste, it just seems a little flat 
to me, so no big deal for me.

My daughter tried mixing it with Gatorade once, but was really upset with me 
because I 'ruined' perfectly good Gatorade and it tasted gross.

Any suggestions on how to make it more palatable to finicky family members?
