Bingo! Yes, 2.5 tablespoons is way too much! FWIW, I asked two different people to to measure out the number of tablespoons in their packages and both counted out ~18 tablespoons, which means that each tablespoon weighs ~10 grams. More math to follow.

Yeah me!! LOL
I poured out my Sav-A-Chick electrolyte and measured it down to an 1/8 tablespoon portions. I only wanted to make a few cups at a time, so I weighed the entire contents, then divided it up to figure out what one cup of water would take. I make like 3 cups at a time for the babies' quart container. But I don't have any of the medicine you are talking about.
