Keep in mind that you are asking on the Water Fast forum.
Also keep in mind that, the thought of one of these making you throw up, is only a thought.
I remember my grandmother when I was a kid, in a panic.
She was ready to move out of her house, and as a kid at that time, I believed her.
It was the thought that she had a mouse running around in her home.
She thought that she had a mouse and she told me that the thought of it was making her want to move out.
I really think that the nausea is due to lack of water to move the loosened toxins out of the body.
