Hi Pamlyn,
I can't say for sure, but when i started induction, i felt very sick for the first 3 days (tapered off on the 4th day). Migraines, felt like i was going to throw up several times... i think it was because of the amount of carbs/sugar i used to eat - and my body flushing them all from my system, while having a lot of fatty foods in it just made me feel yucky. After a couple of days though, i felt much better - i know several people who felt quite sick the first couple days (one friend did throw up). It might just be her body readjusting. I would see if she could stick with it for one or two more days, and see if it subsides? I know that is hard to do, to eat when you feel yucky, but it would probably be worth it to her in the end?
