I was only able to complete Induction on my 3rd try. I got sick and nauseated by day 2 as well. I think the reason it worked the 3rd time was because I tapered off on my carbs & sweets a few days prior to Induction. I still had a horrible headache for about 24 hours on day 2, but the nausea wasn't there this time.

Any sudden and drastic diet change can make you sick. Diarhhea and other GI upsets are common during emergency situations such as floods, hurricanes, etc. where people are forced to evacuate and have to eat in soup kitchen settings.

But I wouldn't want to do anything that makes me throw up. That's why I don't ride roller coasters more than 2 times in a row!
