I'd say that it's likely die off. I would definitely quit and regroup to fight another day if you puke. I puked once taking a parasite drug and I'm sure it was die off but it was more than I could handle. If you're unsure that it's die off, you can always go off it and come back to fight again. It sounds like it might be a little too much. Can you take 1/2 of what you're taking?
