My specialist told me that I would be more prone to nausea because I had IBS.
I don't know if that's the same with everyone, but I found it to be quite true. Like after having a lot of D, if feel very delicate and queasy. In car rides, I always have to look at the road. Even watching some video games made me sick. I wasn't always like that...so I found it hard to adjust. meh.
I would have to lie down for about forty minutes afterwards until my body calms down.
But from what it sounds like, there's no cause or prompting to your nausea which is slightly odd. I'd check with my doctor if I were you.
If I were the rain that binds together the earth and sky,
who all eternity will never mingle,
would I be able to bind the hearts of people together?
