Consistency change in bowl?

I am glad you are seeing a GI dr! If I were you, and it's definitely your call, I would make sure to ask about the retesting and treating issues and let the GI doc take over at this point.
Nausea is often a symptom during recovery. It was one that gave me the worst time. It doesn't sound as though yours is severe but if it gets bad, lots of us have suggestions for what helped us.
Keep us updated and again, best of luck.
