What to do if you throw up half the suprep bowel prep kit?

Finish it: Finishing the bowel prep is the best option. If you have time call the office to get a refill. Be prepared that if your not completely cleaned out then the study will have to be repeated. It is not possible to see through feces to rule out a polyp or avm etc. If you complete the prep and still notice stool then it is unlikely the study will be optimal. You can also ask pharmacist.
