Thank you ladies. If I had taken 2 table spoons, I would have gagged or puked for sure.
For some reason the cup measurements I used had 235ml as a Cup instead of 250, so the quart I drank was about 60ml less than should be. The Celtic Sea Salt was not fine so I used 3 tea spoons -- which was even more salty that I would prefer! :) It was very difficult to drink the last half.
