I was excited to read about sea salting helping with excess mucus/phlegm as I suffer a lot with this especially first thing in the morning. As I had some sea salt I immediately took half a teaspoon with some soup and water. Within a minute I was rushing to the toilet to be violently sick. I didn't then eat until the evening. I so wanted this to work and assume that you shouldn't take it all at once. Please can you clarify how to take this.
