Does serrapeptase cause vomiting?

Syn

I took serrapeptase for 3 days straight I was fine. But then I stopped for 2 days. And I started back up today. I took the amount I usually take on an empty stomach. & maybe 2-3 hours later I began to get a bad headache, and I began vomiting up bright green liquid. I am now in bed. Just trying not to vomit any more. Anyone had this while taking serrapeptase? I’m taking it to unblock tubes.
