Thanks all. She doesn't actually vomit, unless she's in a flare, in which case it's vomiting, diarrhea, pain, the works... she just generally doesn't feel well first thing in the mornings. Nausea and sometimes the LLQ pain is worse in the mornings - and mickey, that makes sense, bc she tends to have a lot of straining and constipation, rather than diarrhea. The diarrhea bouts are very short, just a half-day to a day at a time, and weeks apart.
She loves peppermint tea, it helps a lot.
