Sadly, I don't remember the ne of the mutation, but it is a known, rare occurrence. The docs know how to adjust the dosing accordingly.

I was on everything available for the nausea, but nothing worked. They stopped the treatment on day 9. It took over a week for me to feel better.

Also, for others suffering from frequent vomiting, my dentist just told me NOT to brush afterwards, but to rinse with water and baking soda to neutralize the acid and protect the teeth. This is especially important for anyone with receding gums.
